I'm getting close to finishing the rear swap and I used the old rear springs because they have good ride height for my 275/60-15s. I put new shocks on it last year and they still look new. The front is a different story. I've got 1" solid rubber spacers under the coils and a twist in block or two in each spring to get clearance for my headers. Where can I get new springs for this application, GS big block Buick, auto, no AC at the moment but I have dreams of a vintage air setup within 18 months. Front end will get tubular arms and the rest of it when I tear it all apart.
