Flywheel locks after Bolting Bellhousing?

Hi Folks, figured I would start another thread regarding this one.

Bolting an A833 4 speed to a previous auto crank for an Abody conversion. Motor is a 383 and it’s going in a 73 Duster. I am using the roller style bearing from Brewers. Flywheel spins fine until I bolt up everything. The Flywheel bolts are Grade 8’s I bought and are not bottoming out on the crank/case. I did the 5/8” trim of the tail shaft as well. The clutch, pp and throw out bearing are from a LUX kit.

Could the clutch disc be bottoming out on those flywheel bolt heads? Maybe I need the thinner ARP style flywheel bolts or did I cut too much off the tail shaft and now it’s bottoming out? I’ve had this ***** on and off about 5 times and my back is angry!
