I emailed cpp about the spring rate.
The rear shocks they sell are 180 PSI nitrogen gas shocks.
When we relocated the rear shocks it was mostly to get them into a more vertical position in order to improve ride quality. The rear shocks are also drop shocks so the length did not need to be adjusted much.
On the front when I did the front cross member conversion I removed the 1962 upper brackets and had the 1977 bracket welded in a new location.
