I had the same problem When I installed the Flatout crossmember and changed the motor mounts the yolk didn't have enough engagement with the TH350 trans. I replaced the 4'' yolk with a longer yolk, I believe 6'' yolk from Summit. I don't know if this is another option or if I was just lucky it worked out.
