I have a 85 GT. I may be aquiring a set of Welds. Rears have 275/60/15 d/r's. My GT has Eibach lowering springs now with 245/60/15's(rear). Wheelwells are full now. I have 2 sets of stock springs 99 and 02. Will the rears fit my fox ? I am sure they will fit because several aftermarket spring companies sell 79-04 springs. Will these stock springs make it sit higher or lower than stock fox springs?
