1978 Jeep J10 can't find part name to order

Engine Mechanical problem
1978 Jeep J10 V8 Four Wheel Drive Automatic

the metal gasket between motor and transmission that acts like a stater shim for the starter
? What is the part name and will the parts house have it
/what happened was the bottom starter bolt backed out and the starter bent the metal gasket and now the bent part rubs the fly wheel when running the starter is not engaugeing properly cause of the bent metal gasket
and I think I will have to replace the fly wheel part too
cause
I have to hand turn the engine and find the sweet spot so the starter will engauge the flywheel teeth

thank you andy
