Mounting a muncie to a small block mopar??

Found this one on craigslist....$950.00..Mopar 4 speed overdrive trans all rebuilt with correct 5.5 inch bell houseing, trans yoke, an shifter bracket. Trans was rebuilt with new bearings, syncro's, seals, an new 2nd an 3rd gears I have about 300-400 miles on it an it worked good. This was in my 1967 Barracuda that had a small block also this trans is date coded 1976 or 1977 if that matters, so it should fit 67-76 A-body mopar check to be sure.
