looking to lower rear of 1970 Chevelle

Chris, just to be clear, the Moog springs that I installed in my Chevelle over a decade ago are not "factory" replacement springs for a Chevelle.. What I did was take the Moroso trick spring's specs and found a Moog spring that matched all the specs except rated load as the trick springs were rated for 1800+ lbs. and my nose weight was nearly 2300 lbs. The Moog spring I chose is a heavier wire diameter, .61, rated for 2100 lbs. but the free height and loaded height are virutally identical, so the Chevelle's nose is 10% undersprung.

As to your Calvert shocks rubbing the inside of the coil spring, the fix is to move the lower A arm shock mounting holes outward 1/2", same as required to install Afcos.
