clutch cross shaft "clocking" question

[Howard Nardick]

Is there an easy way for anyone to explain the differences between the three different C-2 & C-3 clutch cross shafts?? 63-66/3832857, 65-66BB/3872962,
67-?/3888279. I believe I own the 67 and up cross shaft and one of the others but I would like to know which "other one" I have...thanks in advance!! HN

Estimate '65-66 BB 3872962 offset about 22 degrees

and I looked at my '65 small block (in the car) and I'd guess about 35 degrees, which explains the longer clutch-to-fork pushrod length.

Am not familiar with the '67-up 2nd design lever.

Check the original GM part sticker on this BB unit.

Bob Jorjorian taught me a simple way to measure the difference between the various levers. With the shaft laying on the floor, and one arm on the floor, measure straight up to the C/L of the hole in the other arm that's pointing up. I don't remember the various dim's for these but it's an easy to check the difference.

I was trying to use a degree wheel when he told me I was making a big complicated deal out of something that was real simple. He was right.
