Convertible Top Cylinders and Lines Replacement 

Just bought new lines for my 67 GS400 due to wear/breakage. Wasn’t going to replace the cylinders but now thinking twice about it. Thanks.

my 69 Olds 442 uses the exact same everything as my friends 65 Mustang - amazing both auto makers outsourced this and it all matches up - I bought my 2 pistons on ebay for about $110 each - as far as I can tell they are all the same

Thank you Dan for this great video!!! I'm in the process of converting my manual Convertible top (Chevelle) to a power top. I bought the whole conversion Kit from Hydro-electric and they gave me a bunch of parts and not one diagram to install. I'm going in blind on this and your video explained a lot of the process. I just hope I don't have a problem with my line coming apart like yours did.

Hey Dan - GREAT video! Thanks for the much needed education!

I just baught a 1968 buick skylark convertible I will definitely follow your steps thank you sir

Thank you that was great and realistic how it would be for me also great steps and advice to do it all not just one side

thanks,,,,,, Now I know what to look for.....on my 71..

excellent! thank you.

thanks for the video!!

Dude, what is that gnarly thing on your right hand !

First, thank you for being so open about the process and showing the issues you encountered. That is such a helpful thing to see!! Overall, your video really was very good. It was easy to see what you were doing most of the time and your commentary helped shed some light on your procedure. A few questions: 1. in bleeding the system, you took out the plug from the motor and filled it w/ jack oil. You then tested the system. I'm assuming you left the plug off and then ran the system? Refilled it to the bottom of the fill hole, ran the system, rinse, repeat until you didn't see any air in the lines? 2. where did you get the hydraulic lines from and what did they run you? 3. I think you said you rebuilt the motor? If so, did you record that process and where did you get parts to do the rebuild? If you bought a new motor, could you share where you purchased it and for how much? Thanks again for the very informative video!!

wow what a mess! always be sure your fittings are set right and tight ,but you did it..

Hello Dan. Thank you for this video. It was extremely helpful. I have a 1967 Oldsmobile Cutlass Convertible and will need to do the same by replacing the motor, cylinders and hoses. My car is completely torn apart. How is the electric harness for the top ran from the switch? Is there a mid junction relay or direct from the dash switch?

Dan do you have a video on how to replace the side panels to get to the cylinders? Also how can u tell if the pump is ok. I’d rather not replace that if I don’t have to

I was watching you install those lines on the cylinders, wondering why you didn’t install O-rings on them or even say anything about

Im bleeding the pump on a 68 camaro and have been leaving the plug in during bleeding and it has blown the plug out of the pump twice. Would leaving the plug in during bleeding cause this?

Do I have to get the exact hose for the car ? I have 68 lemans , and the top lines broke , what would you recommend boss

Do you know the bolt sizea for mounting the cylinders? Mine are all missing

After watching this makes me realize I don't need a pump for my 1964 chevelle convertible malibu 😅

Dan, or anybody out there, is it feasible to disconnect the ram cylinders to make my top Manual?? or, will it be to awkward to pull it up? Too heavy? Thinking of skipping the hydraulics all together. Car is a 1968 GTO, so, GM. Thx, G

Where did u buy those cylinders from?

It's been 2 years, are those Chinese parts still working?

the manual says to use transmission fluid ....

Where's the seal tape the threads
