New Rear Leaf Springs in my 1966 Fastback 

Thank you for the support! :)

Happy New Years to you too! Even the Quick Jack doesn't do enough for me, having a lift would have cut this job down considerably. Next time we'll do it in your shop, I'll bring the drinks!

@@AndyKruseChannel yes sir! Now that's something I can drink to! 🤣🤣🤣

Nice! I'm glad you were able to get those springs off, as you found out they can be a real nightmare. :)

Truth be told, those were installed in November, hence the subtle beard on my face for No-Shave-November. It gets really cold here and I wanted to get a few things done before the cold snap. I'm working on two videos right now that have taken almost 2 weeks and I'm still not done, it's just too cold. Thankfully I'll get them done before I run out of preloaded content. :)

That's good advice. I may want to also loosen the nuts on the shackles and make sure everything sits correctly. :)

245 tires would be nice to have.

Haha, yeah I was wondering when my time was up. :)

Haha, thanks! The Quick Jack would have been in the way (it was the last time I did Leafs on my other '66), so I opted to skip it this round. Even if I did use the lift, it still wouldn't have put the car high enough in the air to really help. No big deal, I had it easy on my last Mustang, this time around I had to make up for it. :)

Good, I'm hoping they settle a little, maybe enough to pull those blocks out. :)

@@AndyKruseChannel do you yave a video with the 1 inch lowering blocks?

@@chevroletbelair1 I do, but it's for the blocks I put on my other '66 Mustang. If you search "How to install rear lowering blocks on a 1966 Mustang", you'll find it. Those are the actual blocks I install on this car, I took them off my other Mustang when I did new Leaf Springs. :)

@@AndyKruseChannel i know how to install Them but wanna see a vid how low this fastback sits Whit those 16" wheels

I was debating about posting on there as I don't feel I'm adding much value to the site with some of my videos. I'm trying to find the balance of sharing my content with enough people so they can easily find it and hope it helps them with their install or at the very least provides some info to the questions they have. I'm also trying to find the balance of posting on other sites but not too much where it seems like it's an attention grab. However, it would be great to see how your car sits now. Caltracks are on my list, they're just behind a lot of other parts I need first. :)

Yeah, I know that cheap shocks result in cheap performance. But sometimes the budget dictates the build. :)

Yeah, lots of options out there.

Thanks! 😁

Since it looks like you're planning to lower your ride with either the mid-eye or the reverse-eye, I'd do the mid eye and know you can go lower with lowering blocks down the road. Especially since you can buy varying heights of lowering blocks to dial in that perfect height. But with the reverse-eye, that's roughly a 2" drop and it may be more than you're wanting. I've got the mid-eye leafs and a 1/2" block in there and I like the way it sits. A reverse-eye would have been too much for my liking, and I can't easily raise the car without doing new leaf springs. :)

@@AndyKruseChannel you are the man!

Wow, that was a while ago, they were on my other white Mustang, the coupe. I looked for them and I couldn't find them, I must have gotten rid of them sometime in the last two years. Sorry brotha! :)

@@AndyKruseChannel NP Andy. Have a good weekend.

I can't recall the last time I struggled so much for a single bolt. Ugh, what a work out that was. Oh well, it's done, now off to other frustrating parts. :)

Wheels are 16x7, 4 inch backspacing (part number VN2156765). Tires are Falken Azenis RT615K+, 225/50/16. With the setup I have, I too can get some rubbing in the rear on certain bumps. But I also have lowered the car and this is the trade off I'm left with. Have you tried rolling the fender lips and see if that does the trick?

@AndyKruseChannel I have 17x7 legendary style wheels. I have rolled the fenders, and no luck. I purchased an upgraded 1-inch swaybar for front to hopefully help with body roll and less rub. I am hoping rear I'd just old saggy springs

@@juanorejel5578 That front sway bar isn't going to do much for the tires rubbing in the rear, but it's still a good upgrade. You're likely correct, just need to replace the old springs with a new set. :)

I did end up going with lowering blocks, but that's ok because I did not know the extent to which those air shocks were affecting the ride height. I currently have 1/2" blocks in there as the 1 inch blocks were too low. :)

Yup, it was the last few videos before this one. Shelby drop and front lowering springs. :)

Thanks! Nope, no rubbing problems with these leafs. Wheels are 16x7, 4" B.S. Tires are Falken Azenis 225/50/16.

@@AndyKruseChannel, Thanks for the info

I had 5 Leaf springs on my last car and they were almost too stiff. I'd say these 4.5s are a smidge softer, but definitely stiffer than a stock Leaf setup. However, my comparison is based off 50 year old stock Leafs compared to brand new Leafs, so I'm not sure how accurate my comparison is. :)

The front is good, but I'm debating about removing the 1 inch blocks in the rear. Maybe swap them out for a 1/2" block? Not sure yet. But the car is getting dialed in! :)

I have been told not to on the new bolts. I'm not sure how I feel about that, but since this is now a fair-weather only car, it might not be a big deal anymore.

I'll try and do an update video down the road to see how much the front and rear settle. Agreed, not using lowering blocks would be preferred as they introduce a larger moment in the mounting geometry, but sometimes the budget dictates the parts. If the Leafs settle enough I may be able to remove them as the car would sit where I want it at that point. I have some ideas of different suspension, but that's a ways down the road, I think this is a decent compromise until then.

@@AndyKruseChannel for sure! I have 1" blocks on my fastback with worn out stock leafs and the stance is perfect, I've been trying to find new leafs that will give me the stance and performance I desire. Thank you for your videos, I've been updating my ride and been doing alot of the same updating you have and your vids have helped alot!

@@nathannelson7020 Haha, no problem! :) My guess is your worn out springs and 1" blocks put you just under "2 inches of lowering" when compared to brand new specs back in the 60's. If you were to install some reverse-eye springs that provide 2" of lowering, it may be too much and then you're stuck. The advantage of the mid-eye gives you and install 1" lowering, but you can go lower with blocks if you want. I prefer s slightly stiffer ride so when I take it through the windy roads I don't bottom out as easily and I get more of a "sport" feel. The 4.5 Leafs springs are definitely stiffer than the stock 4 Leafs, but not as harsh as the 5 (like my last car). I'd say they're more towards the 5 Leafs on stiffness, but a decent compromise for what I am looking for. I say all this in terms of budget. If I had more funds, I'd move to a coilover setup and explore a few additional suspension mods. But, like most of us, the dollar controls my build and I'm not willing to wait a year to save up for rear suspension while the rest of the car sits idle the whole time. :)

@@AndyKruseChannel budget definitely dictates the build in my house hold as well! Thanks again for all the support and info. I'll be installing the CJ PONY parts power discs brakes conversion on front and rear soon maybe ill make a video 🙂

Thanks! Yes, the car has settled a little bit since installing the rear leafs and front springs. I think if I could do it again, I would not cut as much of the coil springs as they're almost too low right now (not, but close). And I would have just gone with a 1/2" lowering block in the rear instead of the 1 inch block. I have since put the 1/2" blocks in place, but I would have liked to save a few bucks. Rear tires are the same as the front, Falken Azenis 225/50/16.

@@AndyKruseChannel I went with double adjustable coil-overs up front to dial-in my perfect ride height. I went with this upgrade when I replaced the tired old stock coils I had cut too much off of, and upgraded the frontend with the CPP tubular upper and lower mini subframe kit. This winter I'm installing new rear leaf springs and I already know I'll order the wrong ones for the height I want. Like you, I'm wanting to eliminate the air shocks and 1" lowering blocks I have now. I like the Global West rear springs with aluminum bushings for better handling, (so they claim). Thanks for your response.

@@jamesyoung6498 The nice part about the Mid-Eye leafs (1 inch drop) is you can always go lower, but you're stuck if you go with the Reverse-Eye leafs (2 inch lower). Just a heads up on the aluminum bushings, while they'll reduce some of the slop we get in our suspension, you'll definitely feel more of the vibration and harmonics (NVH) when driving. If this was a track only car, then you'd be fine, but it may begin to bother you on street driving. This gets compounded if your roads are as crappy as mine. 😄

@@AndyKruseChannel Well I live in Kentucky and some of the roads around here are pretty harsh. Thanks for your feedback!!

I had them custom made at a local shop here in town, no part number. :(

I agree that certain materials don't work well with others, but I have not had an issue with rubber and grease. Maybe I need more time to see if it won't work. :)

Ben een groot fan van je video's en van de fastback

@@franswijnands4022 Thank you! Happy New Year!
