I purchased a set of E30 M3 lower control arms. When I got the arms the bolt that goes to the lower part of the strut was messed up. (When it was removed they left the nut on it and hit it with a hammer) When I try to screw a nut in the bolt it won't catch. Can I re-tap the bolt? I also installed vert front sway bar is there anywhere I can purchase poly bushing for the bar? Also with the 23mm bar up front, will I notice a difference if I order a 25mm bar? Any answers are greatly thanked.
