Flywheel removal question?

The FSM manual ('repair, dont replace' must be their montra) shows you how to cut the welds with a cold chisel and them hammer the ring off. Debur the edges and throw the new ring in a pan of hot water (?) or some heat source and then quickly get it centered onto the convertor before it shrink locks on. then tack weld it carefully so it doesnt warp. up through 67 convertors are small snout, remember that.
