I'm getting ready to pull the engine from my '54 3100. Engine and transmission are stock. When mounting to an engine stand, I know you're supposed to mount the engine where the transmission attaches, but the original bolts aren't long enough to fit on the stand. Does anyone have an idea of what size I should be using? The bolt hole on the engine stand is 2 inches long. In addition to recommended length, I'm also looking for diameter and thread for the stock bolts.

Thanks,
Brian
