I just purchased the Muncie that the previous owner had removed from my 67 Camaro. I do not believe it to be the original, but I am wondering what it was out of.

It has the two grooves on the input shaft, so I believe it to be a M20 wide ratio. The assembly date code is P2R04A. I also found the engine block vehicle code on the top of the case. It is 32R122118. Also, the spline on the input shaft is much finer than the pictures of the input shafts in MacNeish's Camaro fact book.

Any help is greatly appreciated. Thanks!

Its a 1972 model muncie M20 wide ratio probably out of a Olds Cutlass based on the partial vin number...

Thanks again!
