Years ago I tried SS springs for my spring wrap problem on my 67 GTS with a manual trans thinking it may help. In my case I had no difference from the original springs. Stock snubber was not doing it's job even after addressing that still had what felt like clutch chatter but was spring wrap. Ended up going back to stock springs to get rid of the truck like ride and clamping the springs with actually helped along with an adjustable snubber. Caltracs would have done the job but you loose the stock look and ground clearance.
