Buddy of mine wants to redo the suspension on his '53 3B. Anyone suggest a current supplier of quality stock height (or 1" lift max) replacemment springs? I bought some Omix ones years ago and they flattened out with just the weight of the f-head.....wasn't impressed. He has the "C" shackles still in place, would like to keep them if possible. If you can help me guide him to a decent quality supplier or kit, I'd appreciate it.
