What are the differences between a Saginaw and Muncie 4-spd trans???

My neighbor has one that he 'may' let go, but has no idea what it is.

Casting numbers on the right side of the case and bearing retainer are:

3851325---Case---also has cast in "GENERAL MOTORS CORP" on passenger side.
3851326---Bearing retainer

are they aluminum

A Saginaw 4-speed has all three shift levers on the side cover. A Muncie has the reverse lever on the tailshaft.

also a Muncie has an all aluminum outer case:thumbsup:..........the sag,cast iron:(

Those are early Muncie casting numbers (64-65), plain and simple. :thumbsup:

Thanks, Guys:)

Tom---are you on another board I frequent? Got nearly the same exact answer there as well:D
