if its from a 60's truck, i believe that it came originally with a muncie. heres how you can tell............the plate that has the two shifting arms on it bolts onto the tranny with four bolts, the saginaw bolts on with seven. muncie trannies were painted blue...saginaws werent painted. (at least i havent seen one painted) Also, muncies ARE shorter than the saginaws by about 3 inches, someone here told me they are the same length but theyre not, i have both. they share the same bellhousing tho. i hope this helps
