Trying to decide what bushings to put in each car. The b4c 1le that I own I am willing to install tubular control arms in so that's not an issue there. But do they make rubber bushing control arms vs poly? I was I was hoping to maintain the nice smooth ride quality of my b4c and keep road noise to a minimum. It's just a daily. As for my formula 1le. I'm definitely keeping the stock control arms. However I can't seem to find any part numbers for factory replacement rubber bushings? Any help? The formula 1le will be restored to factory spec.

82-92 Front lower control arm - Rear bushing GM 14039484
83-92 Front lower control arm - front bushing GM 14039483

1LE not broken out as with some parts, I'd assume they received same bushing. In other words, same bushings used during 3rd gen production for all cars. Not sure what happened to 82 rear bushing.

I'm wanting rear lower control arm bushings. Sorry should have specified. But also fronts are beneficial to know. Mainly looking for rear at the moment.

probably the same story, same part for all cars. I've read to keep rubber in these parts, don't recall why, or if that is accurate, maybe poly binding. point is, I'd search around and study it before doing so.
