What can happen is that the fork extends too far into the housosing it it's not correctly seated on the stud. With the trans input shaft in place, that forces the throwout bearing too far onto the fork. The rear lip of the throwout bearing that holds it on the fork can then catch the inside of the fork, cocking it and jamming it.
That or you've mounted the throwout incorrectly on the fork or got the wrong for.
Shoot a pic or 2,

I agree. It should be in the center of the bearing. Are you sure you have the correct fork? I think I remember there were several different sizes. Or maybe there were two different sized pivot *****

Well, I will probably need to replace the fork now anyhow, any part number recomendations?
BUT is that whats causing the problem putting together and takeing apart? seems it would be silly to put it back together till I knew. but at the same time the thing is in pretty rough shape if it rains, I am screwed.

I am useing the 621 bell, and the fork that came with the car, no saying what the fork is off from really. not the corvair I am sure, maybe the Corvette the motor came from, or the trans am the clutch came from.
What fork goes with the 621 or what fork should i get?

There's your problem. Corvette forks have a pin attachment for the Z bar. Most others have an indentation that a rod simply is held in by spring pressure. How is your clutch linkage set up? Also, what throwout bearing is that, and what are the dimensions?

I am not an expert, but dont want to see you have to pull the engine several more times. I think there are 2 pivot ball lengths & 3 throwout bearing lengths, and all of these relate to the clutch/pressure plate and fork being used. If the geometry is off you may not have have proper operation. And (not saying you did this) but the bearing can be installed improperly on the fork.

I am going to price new shocks tomorrow when I am (hopefully) getting the new clutch fork.
Shocks on it are "brand new" from 1985 and have never been driven on, but they are ugly and dirty and a bit rusty, and I want it to be pretty.
I am going to go to the auto parts store and order a clutch fork out of a 68-72 big block car and hope it works.
I really want to get the motor and trans back in so I can install the drive-shafts I spent hours cleaning and painting and changing the U joints in.
The drive shafts have never been installed since 1972 and I get a real kick out of any part that I put on that I haven't put on before,.... I need occasional progress to keep me going LOL

Nice link Gary, I will have to file that one, it could come in handy.
Crazier, don't get discouraged, it will be worth it when finished. And I hope the rain cooperates.

Thanks 74, I was hoping to source something locally, rather then pay shipping and wait forever, but the one was real close to me and free shipping.
I just thought it was a little strange taht nearly all the auto parts stores could get the 73 fork, but none of them can get the 72 fork to save their lives.
