Choosing a rear suspension

LOL, well the SS springs are probably no longer being made since Fiat took over. I’m sure they’ll go up in cost! The A body springs cost was silly.

Reasonably priced replacement springs I got from espo.com (Springs and Things)
I ordered them in a 1 inch overbend 6 leafs each side. Launched straight as an arrow. Road great.
