My guess is that your problem is in the bellhousing. The clutch fork should angle towards the front of the car when it contacts the pressure plate fingers. If it does not the fork goes over center and wants to pop off of the throw out bearing clips. The reason for this anomaly is that the new aftermarket clutches do not have the finger height set correctly. In a GM application you can adjust the dth of the clutch fork pivot. Because the world is dominated by GM cars nobody ever thinks to check anything on a Mopar application. I have had to correct this a few times, most recently on my 68 GTS.

I`ll bet you need to make a spacer for the clutch fork pivot and or a longer pivot to correct this.

Get a pic of that clutch fork angle please. Do you know what disc and pressure plate is in it?

If you cant fab something up surely we can get one of us with a mill to hook you up. I made my clutch fork pivot out of 2" x 3/16" thick angle iron.
