I am converting powerglide c1 to manual trans. Orginal manual cars had the cross bar stud on bracket what was mounted on cast iron bellhousing. This has newer engine and aluminium bellhousing without place for cross bar stud bracket. Is the stud mount on the block in correct postion?

I cant double on the frame mount because I need to weld that too on automatic car frame.

probably won't work for this situation, but is food for thought.. this is a bracket that was made for the engine end ball for my ZZ4.

I converted my 61 to an auto. I still have the frame sitting around. It looks like the ball needs to be about 4 1/8" forward of the back of the block. The hole in the block is not in the right place unless there is room to move the mount you are attaching to the frame back and then use it as if it were a later style. The ball is approximately 2 3/4" lower then the hole in the block also. I do have every piece of the oe 4 speed linkage and pedals.

Great drawing!!

Is that supposed to come between those to later style pivot ball holes on the block? Little bit angle?

Sorry about bad pic..

Yes I could weld the frame part in newer style location, but I am looking for oem style assembly. I try to measure it

Could this be close enough?

I did the same thing. Its customized rather than bubbaized.

Mine is more of an L shape on its horizontal. The long section is where the bolts connect to the bell housing and the first hole in the engine block. The other part is lower which matches the clutch cross shaft. I did have to grind down the side of the engine casting where it stuck out. Then used the flat tab section.


Something like this:


Also had to shim it so it sits flush. Plus some grinding on the side of the block to make it a smooth transition.

That's close. The ball should be about 3 3/4" from the rear of the block, I just measured again. And down 1 13/16" from the holes you have the templet bolted to. That should get you real close. Jimh slipped one in on me. I was referring to your post

While I was there I added zerk fitting and poly bushing to Z-bar.

I put a wooden dowel in mine then added two zerk fittings.

Also ditched the rubber/steel bushing and went with a plastic/bronze one instead.
