Froggy, got the springs you reworked with your seawater refurbishing. MAN WHAT GREAT SPRINGS. I checked them out and they produce 8.5 more pounds per inch than the hi-po springs I been using from ford (vintage 1971) I'll be putting them on for this weekend coming up at nelson. Look out I feel a track record coming on The purple strip is a nice touch. I think you should patten the idea and lets sell them. I might have another set of vintage springs laying around.
