the springs i got with my rear suspension were 14" high 3.5"id 4" od. they are a bit too long, would like to have 12.5 high. i already trimmed 1.25 loop off each, got it to about where i want it, but would like to have correct height uncut springs. i dont know where to find a chart on moog stuff or others that would work. and help would be greatly appreciated.
