So after a couple more hours of searching on the web I'm pretty sure these control arms are from a S10... Which makes me wonder if the front subframe is actually from a S10 as well. Considering some of the half@ss jiggering the last owner did to the truck it wouldn't surprise me.
Looking at the pricing for new control arm parts, it would be close to the same cost (including my labor) to buy vs. repair the old ones (replacing bearings, bushings, etc).
Does anyone have any opinions concerning aftermarket parts? Mevotech, Moog, McQuay-Norris, Dorman? All the reviews tend to be mixed since most parts are being made in China now. I'd really prefer to only have to do the job once.
