CPP Rear Coil Spring Specs - 60-72 C10

[mrlush]

I purchased a set of 5" drop rear coil springs for a 63 C10 (part # RCS603-5). I need to set the frame at ride height to setup the chassis and rear pinion angle.


Since this is a body off resto, I have no weight compressing the springs. I am looking for specs on these coil springs. Here is what I know:


1. Full unsprung length is 9.25"
2. Approximate travel is 6.5"
3. Approximate max compressed length is 2.75"


Does anyone know (or can measure) the coil length loaded with a full body installed?


Thanks a million!
