I've heard most tubular arms like Global West are made from 1.250" X .125 DOM tube. If the arm is made of bent tube, the DOM is easier to make good quality bends in than 4130, this is just what I have heard, I have no first hand experience with doing it but I have bent 4130 sheet into a tri-angular tube and welded it into an A arm and it was very tough to bend.
I've seen Alston A arms for a Nova that were 1" dia mig welded, don't know the material though.
