Great replacement for Helix lower control arm bushings. Used a ball hone to remove powder coat and polish before pressing in the new bushings. Fit perfectly!

Can these fit other MII tubular control arms? The bushings on my mustang II tubular control arms are worn out and need to be replaced. I originally used a Fatman Fabrication stock mustang ii front sub-frame w/ the tubular upper and strut-less lower control arms. Now after 17 year the bushings have gone bad. I asked a local hot rod shop if I could just replace the bushings and everyone has said I have to replace the entire control arm. These are the first replacement bushings I have found for a mustang ii tubular control arm. So my question to you is are these a fairly standard size so they could fit my set up or are not all mustang ii tubular control arms built to the same dimensions?
