I forget what you call these things. Rear end bump stop bracket with mounting bolts. Pulled from an Olds 8.5" rear. 50.00 shipped located in northern Virginia IMG_4367 by azstage1 posted Jan 12, 2019 at 11:08 PM IMG_4368 by azstage1 posted Jan 12, 2019 at 11:08 PM
Should be same same Todd. These were on a 8.5 10 bolt that was under a 70 GS455. I swapped the rear in that car to a correct rear and no longer have the rearend.
Todd, Yes they are the same as on the GS's, and the metal looks in great shape. All you have to do is take the snubbers out of the rear and install them in these. Duane
Can anyone explain why Buick put these on the GS? They apparently limit suspension travel. Why? Why not just install a taller rubber bumper and not a new bracket? Sorry for the thread hijack.
You asked so............ They were used for exactly the way you described, but the cars already had the taller rubber bumper. Those brackets are the same ones used on 68-72 El-Camino's with the shorter rubber bumpers. GM already had the parts in stock, so why would they spend the money to make a new part if they did not have too??? It was simple for them, use the El Camino bracket and the Buick rubber bumper. Zero cost to give them what they needed. Duane Also sorry to hijack the thread, but the sale was over.
My thoughts were they were trying to stop the axle from slamming up into the frame, by not giving it too much room to move. (Not that any of us would ever do something like that under a hard take off.) The Chevys with the 12 bolts, and some Buicks like my 69 (with a 12 bolt rear) had a single rubber bumper and bracket directly above the rear pumpkin. But they used the regular rubber bumpers on the rear axle housing with no brackets. Often different manufacturers used different parts to do the same thing. Duane
