Does anyone know what other GM cars front lower "A" arms fit the '70 GS? I have a bent one I need to replace. Thanks Don
Let me know what you find, I'm in the same boat with my right lower control arm. Larry Long Live the A-Body!!
If you guys need control arms, I have the original pair of lowers off of my 70 Skylark . . . I'm not gonna use em, since I've opted for a global west setup. Shoot me a PM . . .
Other GM divisions used holes in the control arm spring pocket that are in a different place than Buick. The reason for these holes was to line up the end of the spring so you could see it through the hole. I was sent a control arm from a western junkyard that they said it came off a Skylark but the hole was not in the right place. I think the Buick had an oval hole and others have round holes and other makes are in a different position. Any will probably work if you just know the correct position of the spring from the service manual. With replacement springs they probably are not as specific anymore anyway making the holes less relevant as a few sizes now fit many. Personally I would only use a Buick lower arm for this reason.
