OK just to be the odd man out I have a 67 Nova with a Heidt four link in the rear. Changed the supplied single adjustable to Afco double adjustable and it made HHHHHuuugge improvement on ride quality. Compression, rebound there is no comparision. If you go with Heidt four link tell them to keep the supplied shocks and go with anyone else's double or triple adjustable shocks and springs.
