I never see 1" drop spindles advertised, anyone ever see them for sale? That would be for a 65 Skylark.
A single inch should be capable by simply using shorter lowering springs. I've never seen a 1" drop spindle, only 2" since you have to compensate for geometry changes when you drop too much.
ATC afx spindles are 7/8 drop and are about the best spindles you buy along with their steering arms..possible bad thing is you have to run 17+ rims you may get them from www.scandc.com another option if you insist on keeping 15s would be L&H kustoms spindles which you may also get from the link I posted above ps you can get tall "stock height spindles from L&H and should still lower youre car a tad due to the relocated upper balljoint ..i'd also get their matching steering arms(lower balljoint angle) to fully correct the bump steer
