I have a frame for a 69 to 72 Skylark / GS comes with a 3.73 8.5 posi rear built by Jim (V8 Buick name Monzaz ) this rear doesn't have 1000 miles on it. There are also UMI upper and lower control arms, new rear coil springs, a new driveshaft from Driveshaft Specialist out of Texas. All the bushing on the front end are new as well as the ball joints, rotors, calipers, brakes, tie rods, idler arm, centerlink. The only thing in the pic. that isn't included is the transmission,4 shocks, trans cooler, braided fuel line, and 455 frame pads. frame pads can be left on if you have a set and want to just swap. $2000
