I'm measuring the control arm its self, from the outermost part of each side (the place where the bushing shoulder is supposed to seat) on the R/T's control arm it is 10 3/4", and on the S/E control arm it is 11".

I know I didnt bend them when I installed them because I installed the bushings one at a time, placing one end in the vice, then the other, so that it could not be pinched. Also, both control arms from the R/T are the exact same width. Perhaps Joe mechanic who installed the bushings in the R/T before we got it pinched them?
