Clutch fork picture

[LOLO]

Anybody have a good picture of a Big Block Buick clutch fork, close up and of both sides, maybe even some measurements as in length and width?

Ricardo,

Here are 2 pictures of the clutch fork for a Big Block Buick. These are very hard to find and often the tabs are broken off on the spring steel throwout bearing retaining clip.

These are the only 2 pics I have on my work PC

This the one I took out of my '71 455 car. It isn't the original (I have it somewhere around here). Mine has an additional bracket welded on the back. :Do No:

I just ordered that adjusting arm on the left of your pic from Dave Kleiner today. The swivel on the end was worn through about half way.

Ken,

The clutch fork I have on my GSX also has the additional welded on return spring bracket identical to yours. That's why I picked up the second clutch fork. Do you know car what that is from?

Thanks for the pictures everyone, Im wondering how hard it would be to modify a clutch fork that I already have, its not for a buick, I was looking to see if the bends were about the same, I could always make and weld the right end piece. I know (Dave Kleiner) "spelling" makes them just wondering how hard it would be to modify one?

Why would't you be able to use a regular GM clutch fork instead of the one with the clevis pin? As far as an adjusting rod, Mr. Gasket sells one for the more conventional fork. My 73 Stage 1 had the more common style.

You could use a push type cup, adjustable rod and clutch fork that Buick used in 68/69 BBB but there is no "regular" GM A-body clutch fork.

In the threads that were lost here a lot was learned about the specificness of Buick clutch pieces.

[buick64203]

I was under the impression that GM passenger car clutch forks were all the same from 64-73. OPG lists what looks like the same type I had in my 73. Although they list it as "66-72" .

[greg davis]

They arent, there was lots of discussion and trial and error from others, even the pedals differ form chevy to Buick

I can definatly agree with Greg that Chevy parts do NOT work in a buick. I strongly recomend Dave Kliener or Year one for these parts. The parts from Dave are the most accurate I have seen, and believe me, Ive bought every clutch piece I could find, and non of them worked, except what I bought from dave.

I've found one problem with using the cup style "chevy" clutch fork in place of the "clevis" style. The "curve" of the forks are different. By this I mean the attachment point of the adjuster rod is further forward on the big block "clevis" style. The reason I found this out was my cup style fork was hitting the rear of the fork opening in the bellhousing because it was flatter so to speak.
I cured this problem by using an adjustable pivot ball in the bellhousing which brought the attachment point forward again. :Do No:
