I put a set of Hotchkis springs on my '67 in hopes of dropping it about an inch and a half. This did not happen, in fact there was no change at all. I had multi leafs on it and the ground to top of the fender lip is exactly 28 3/8". I did post this in Bench marking, but my question is what is the right height for the rear suspension? I believe I am to measure from the center hub to the lip, but in all the books I have I can't find a number.
