I wish I still had a picture and I just finally sold it about a month ago now.
I'm so happy with my new T-5!

The old 4 bolt side cover was a Muncie (non syncro 1 st gear). that trans showed up in many different trucks/cars from about the mid 50's, & had some different lenghts on the tailshafts. Along about 66, the cars pretty much went to the saginaw 3 spd,but trucks still used the old Muncie for a few yrs. To the best of my recollection (thats scary!), the lite duty 6 cyl trucks 67-68 had the old 4 bolt muncie, whereas the v8 sb trucks had the saginaw. 69 made the saginaw standard equip in the lite trucks,(6 or V8 all the same). The heavier 3 spd Muncie(full syncrow), & the borg Warner were not really common in our trucks, but IIRC, were more of a BB v8 deal. L
