3/4 ton springs

[rockhop051]

Quick Hello to everyone on the board from a new guy and thanks for all of the great information already passed along.

I've got a 66 3/4 ton custom camper that rides like a tank and I need to soften up the ride a bit. Can I swap out the coil springs with a set of 1/2 ton springs and get some relief? If not anyone know an easy way to soften up the ride?

Also I'd like to find some new 8 lug wheels to go on it and was hoping to pick up some used ones off of CL. Will any Chevy 8 lug rims fit or only from certain models?

Thanks Everyone.
