I had no issues installing Posies Super Slide Springs. The bare rear aligned easily before welding on the axle brackets and all the associated Posies and Speedway spring parts fit perfectly. By Mr "D" on September 28, 2019. 30 years ago when I converted from a closed drive line to an open I set up my rear-end housing mounting to allow for the offset thus not needing to change the springs. Well after several years of running the modified 235 cu in six cylinder with a Muncie 4-speed I converted to a SBC 327 and a turbo 400.In this process I installed new Posie super slide in the front along with power disc brakes and power steering thus keeping the original axle. When measuring for the drive shaft I took a good look at the rear springs which were very tired so the posie super slides were ordered for the rear.
I was going to use the same rear-end with my modified mountings, I didn't need the posie offsets. Related Items / Suggested Parts. Speedway 1947-54 Chevy Half-Ton Axle U-Bolts, Set/4. Posies 450R Shackle Rubber Replacement, 37-54 Chevy/GMC, Rear.
