Back in the day drag racing. Ive tore up dozens of those Muncie 318 transmissions. I would take parts of several and build one. It wasn't never any big deal for me to take one apart and put it back together. Today Ive got a good supply them. I even got two of the 319 overdrive ones. Ive sold a member named Dellman two of the 318 three speeds for his trucks. good used transmissions for $100 each.
