So I dropped my winter savings on suspension and seats for my Mach 1 and now im down to the last piece of the puzzle. Spring Isolaters. This wont be my first suspension swap but last time I used Poly and will never again suffer through that squeaky hell ever again. Ford quoted me over 260 for a full set of isolaters and mine are pretty much shot. Im not too worried about using the old ones but would prefer to use the new ones. Does anyone know of a set of rubber Isos? I will just use some rubber heater hose if need be for the front lower isos ( good results according to some people on other forums, but the rest of the isos. Also, does anyone know what the inner and outer diameter of our springs are?
