I don't have a Chevy and I'm not familiar with all the combos, however.. If you just space the trans away from the bell housing with a spacer plate, what will keep the trans input shaft on center with the crankshaft? Don't the centers rely on the bellhousing bore indexing with the input shaft bearing retainer?
I once had a drivetrain that was spaced this way using a 9/16"
steel plate.. The centers were off due to this method and the synro ring cracked after a while..Kinda inconvenient when you're miles from home and can't shift into high gear....
