Greetings from a fellow Montanan! Just came across your channel. I’ve got a 79 f150 that I’m going to start freshening up this spring so,it’s good to see someone else going through the process. Good luck with on your journey. They are great tucks. I’ll never part with mine!
As Kevin Bailey said, the spring is for behind the door panel to help seal for the window crank. . It possibly holds a flat plastic washer or the paper against the back of the door panel.
Are you kidding me? It's like this channel is a biography of my life! When my first son was born I was able to by y first Ford back, 78 f150 Ranger, very option for 78. Definitely giving me motivation to get my kids out to the garage and get it back on the road.
You chose a straight thru muffler. It's going to be loud. The tailpipes will help a little. But when you get on it, you and all your neighbors will know. If it is too loud, throw a decent length glass pack in each pipe before the muffler. It will help tone it down a little more. And if you ever need to change out the front brake calipers. A good cheap up grade are the mid to late 70's T-bird Front calipers. They fit right in place of the truck calipers but have larger pistons.
I see a couple of answers to what that spring is? Maybey I'm mistakin but I thought it looked like a spring from inside front locking hub? Aftermarket hubs don't have the spring.
