When I refreshed it three years ago, I replaced rings, bearing and gaskets, that's all.  So it was still essentially balanced for the flexplate and auto trans.

That's why the shop wants me to bring the flexplate (from the original build) and the flywheel/clutch.  They'll check the     balance of the flexplate and try to match the flywheel and clutch.
