I used one like John Kunkel's for years. It gets the job done simply. Mine had the rear supports go to the factory rear lugs and bolted.

I later made this one with the Mopar BB and SB bellhousing holes. It is nice to be able to either have the pan side up, or rotate to have the tailshaft end down.
