There was a different frame used on the 60-62 models versus the 63-66. The rear ends were different between the two models also, as were the shock mounting location, spring locations and the trailing arms mounting locations. In the research Ive done, the rear springs from 60-72 are interchangeable. The front end of the 60-62 used torsion bars, so no springs there.
