Do you realize that the information you posted in your latest post #29 contradicts the statements you made in reply #27? If the bellhousing is original to your car and it has the wire clip type pivot point then the fork that was original to your car will have that same wire clip which is the one on the top in my picture. The fork on the bottom came with the tongue type clip from the factory . Even if you modify the later 68-70 bottom fork to accept the wire clip the visible end portion has a quite different incorrect appearance . That is if historical accuracy is important. Just wanted you to be aware just in case you were confused about the differences between the two.
I might have misunderstood your picture Bob.
I'm confident that my car does have the original bell housing and has the original wire-type pivot point. I believe I have the original clutch fork as well which has the wire retainer. If I'm understanding everything I've seen to date, there is and early 67 version with a wire-type retainer (top of your picture picture), a late 67 to early 68 version that also has a wire type retainer but a different end similar to the 68/69 version (what I have pictured below), and the 68/69 version which transitioned to the clip-type retainer (bottom of your picture).
Didn't have time to cross reference the part numbers this morning but I'd pulled three different numbers previously that appeared to support the above.
