C2 65 L79

[Mike M.]

I'm trying to make sure the clutch rod that attaches to the clutch pedal and goes through the firewall is the proper one for my car. I would like to know the length that the rod should be. If anyone knows this or could measure one and post the length that would be great. Thanks Mike

The GM #3819154 (63 through early 66) or GM #3888213 (late 66 through 67 and all 63-67 SERVICE) pedal rods are 19-3/16" in length, end-to-end.

That explains things, why I was having problems ajusting the clutch before I took the car apart.The rod that was in my car is 18in long. Are there any differences between the 2 parts GM#3819154 & GM3888213?
Thanks Joe

Well, as I check I find that the 2 pushrods were of different length. The GM #3819154, used in PRODUCTION from 63-65 (except L-78), was, indeed, 18" long. So, the one you have is original.

However, in 1966 GM changed the PRODUCTION pushrod to GM #3888213 which is 19-3/16" OL. They also changed the 63-65 SERVICE pushrod to the 3888213. So, that pushrod should SERVICE the 63-65 application, even though the 63-65 application originally used a different cross shaft than the 66+. If you use the 66+ crosshaft, GM #3888279, then you MUST use the 3888213 rod. If you have the original 63-65 crossshaft, GM #3832857, then you should be able to use either the 3819154 or the 3888213 rods. However, the fact that GM replaced the 3819154 with the 3888213 for all 63-65 SERVICE applications and did so as early as Novemeber, 1966 IMPLIES that they might think that the 3888213 is better for all the applications. Of course, it could also be that the 3888213 was functional for 63-65 applications and they wanted to eliminate a part from SERVICE inventory requirements. But, I would bet on the former theory.
