T90 Clutch bracket to GPW frame

Post by Gunny » Fri Sep 10, 2021 9:52 am

Greetings All,

What modification did you have to do to align the clutch bracket on the GPW frame? It appears that the bracket on the frame needs to be moved back a bit. Any pictures would be greatly appreciated.

Move it rearward 1.250". You used the cj2a crossmember with the deeper drop did u not. Did u redo the body floor at tranny top area or did u lower the crossmember even more with spacers or something.? Then u may have to lower the mount location at least the same as the spacers.

The tub is off, haven't modified it yet. I lowered the cross member. My concern is that it's a GPW, so the frame is not open like the MB, will I need to modify the frame as well?

You will need to trim the frame reinforcing there, the hole is teardrop looking, alter it a little, give it some free room so it will not bind if tranny mounts are flexing a little, if tranny and t case and engine are in there, it is easy to locate. Captive nuts should be on the bracket, just drill 2 holes of where you want it.
if u lowered the tranny and the t case sits lower than stock location you will need to lower the bracket that much. Without knowing how u lowered the cross member, as i have seen hack jobs relocating the original cross member brackets, and spacers put in there and what not.
If you have the link from pedal assy, to the z bar, you can check that too, I have not seen any repo that are the correct length and the geometry gets all out of wack.

I have a 44 GPW with a T-90 in a 43 frame. It was very easy to move the crossmember and clutch linkage. I will post pictures or PM or PM for a call for info. I am very Happy with the results.

I had a '45 GPW with a T90 (and a CJ2A transfer case with internal expanding parking brake) and IIRC the pivot bracket was simply moved back by using the original rear hole and captive nut as the front hole, and a new hole drilled for the new rear hole. It had a (lower drop) CJ2A crossmember and (high clearance) CJ transmission cover, with the rearmost portion of the transmission access hole in the body/floor cut slightly and bent up under the 2A cover. I didn't do it, but I did leave it that way because it all fit and worked just fine. I sold it over 20 years ago so no chance for pictures.
