This brings to mind a truck I helped a friend do an engine and 700r4 swap on. Prior to him owning it, someone did a body off frame resto. Black truck with red frame (?). They installed a 350 and th400. They used 3/8 bolts in the engine frame stands and on the trans crossmember they put new longer than original bolts in from the top. They must have done this before mounting the cab as we couldnt get the bolts out as they hit the floorboard. He had to cut the heads off with a sawzall. My buddy pulled the frame stands to clean and paint them. He couldn't get the engine mount bolts to line up. I told him he needed to buy 5/16" bolts for the frame stands to allow some tolerance. He did so and it went back together fine.
