Day 1, project trans am series 1965 dart

for those who dont know what a grand national rear is, this is it, a ford 9 inch with a large nut, a machine surface at both ends, a hub assembly with 2 large bearings come together, a drive plate and a center cap that holds the axle in place, its also call a full float rear end, since both ends of the axle are splined, no tulip end that goes to the wheel....you can quickly change the center assembly, by simply removing 3 allen bolts on the center cap, pull the axle out, swapped center section and reassemble without ever even taken the wheel off, i can swap the center pumpkin at home, 2 guys in less the 10 minutes, at the track less than 15/20 minutes
