I'm still working on it. I made a longer slave rod to clutch fork and that didn't change anything.
I did go do some research on the clutch kit I bought and using the models and numbers provided in that other link:
By cross referencing the makes and model there with Rock Auto kit numbers it looks like I ordered the correct kit from Summit...MU5505-1. The picture for the '72 Chevy Blazer clutch fork looks like mine too.
So I'll do a little more digging to see if maybe the clutch fork has become disconnected from the throwout bearing. (I didn't think that could happen)
I have noticed the clutch pedal pressure need to move the clutch fork is very low with new master and slave. It isn't low enough at fork for me to move with my hands or anything like that.
I guess this has been a good thing....it gives me something to do while he's off at college.
Any other ideas would be greatly appreciated.
