go to junkyard
if you want new control arm pdm is great deal, cheaper than most dealership even after a discount, i dunno what norcal drifter is talking about but im pretty sure don told me they are oem, maybe i am mistaken. also the option of the poly bushings pre-pressed is really cool, if youre gonna do this replace both, great mod in conjunction with the pillowball t/c rods. also check your tie-rods to make sure they arent bent
this is from spl-parts page they have all the parts you need as well
