I think you are going to need a V-8 center link from a 63-66 A-body car. They may be shorter than the later years. I am doing the same swap in my 66 Valiant with disc brakes from a 73 Duster. Make sure to use the lower ball joints from the newer set-up. The other stuff will work from your Valiant (pitman, idler, etc) Your Valiant lower control arms will also work with this swap. I have also heard you should use STOCK rubber bushings for lower control arm bushings and the strut rod bushings! Poly ones squeak real bad! The rest are great to use. :thumbup:
