On the 427 frame shown on the facebook page they didn't make different chassis pickup points from one side to the other. That shows tubular with Girlings one side, K billet the other. Kirkhams claim from the beginning was that their parts interchange with originals. The mounts are the same but Steve will be able to tell us if they adjusted arm lengths at all for rotor hats on the outside of the pins or anything that changes track width.
There are original tubular Metalistik bushed arms, the same thing bronze bushed for Comp cars, there are early CSX Vegas/HST style with turn buckles and heim joints for added caster adjust, there are South African HiTech arms with turn buckles and heims with straight tube triangular arms, then there are late Shelby ones with screw in Chrysler style ball joints for the billet uprights. Kirkhams have also been through a couple of revisions as they improve geometry and manufacture methods. They have added heims to tubulars, made billet ones, made billet ones with improved steering points to virtually eliminate bump steer with Morris. Other than the 289 and hybrids which is a different deal they all will mount the same.
