Maybe if Davescuda comes back and tells you the SS vin guy has that on file, then yes. Until then, it's a converted B body trans and that's not the answer you want to hear.
I did no less than 10 of these B to A, 18 spline conversions back in the 80's.
Those shift rods won't fit any A body car I've ever worked on without some serious mods. Definitely not SS shift parts
Marksmopar1 transmission is a PERFECT example. No A body cars from Lynch Road in 1968 from what i recall.
Definitely NOT a super stock race hemi trans, as it is still fully syhncronized, the race transmissions were "slick shifted" and didn't have the brass syhncro rings in there.
