You pretty much have to use the flywheel that fits the crank.

Make sure the diameter is the same, or the starter won't work.

They changed the balance of the engines when they went to 1 piece rear main seal, as well as changing the flywheel. They also changed the bolt pattern of the flywheel when they did that. If the flywheel will bolt on, it will work. It's foolproof! Gotta love GM for things like that.

If your old wheel is the 14"-diameter 168-tooth version, PN 10105832 is probably what you need.
