Raising the rear

Yes Yes - the air shocks were a fix the previous owner installed to combat the sagging springs. Obviously not the long term solution. One of my other projects rolls on a complete airbag suspension... trust me I know the impact (no pun intended) that an aired up suspension imparts.

I really would like to find a spring solution. I've combed through a dozen or so threads here - and that's where i found the link to the springs i noted. The S/S springs come highly recommended, but I'm concerned they will also not provide enough lift to obtain tire/fender clearance.
