Re: T56 clutch fork pivot

Check with a Tremec dealer. The pivot is part# 1386-183-004 and the pivot bolt is 1386-149-001.

Tremec Dealers:
www.thegearbox.org
www.ddperformance.com
www.autogear.net

Since your in TX, might want to check with Mike @ http://www.txmotorsports.com/ also..

I haven't been through that whole list yet but this thing is proving to be discontinued. If any one has one would you do me the favor of taking some measurements for me. I'm just gonna make one

Do what Mike suggested instead of calling the GM dealer.

Re: T56 clutch fork pivot

Looking at it as the "T" shape
top width = 1.200"
trunk width = 0.475"
depth/thickness = 0.600"

The "arm-pits" of the "T" are actually semi-circular for the rotation. The are 0.400" at the thickest, and bevel around to both front/back edges 0.200" thick.

The bolt hole measures about 0.333".
