Here is an empty 3925660 4-speed Muncie case with a date code of P8C22 ( March 22, 1968) and a VIN code of 38514734. It has a 1" bore, and the cluster pin hole is a little loose. Someone did a good job of welding the two ears back on; see the photos.
The case is in good usable condition, all threaded holes and flat surfaces are perfect. The case is factory original from 1968 to 1970, but it can be used for all 1963-1974 GM cars, including Chevelle, Camaro, Nova, Corvette, Pontiac Firebird, Tempest, and Oldsmobile F85 & Cutlass models.
