What a coincidence, I also have a 68. I made precise measurements to insure that the wheels would neither rub nor stick out and they came out perfectly. In order to accomidate future lowering coils if need be (I want it to sit a little lower than stock) I set the wheels in 1/2 of an inch from the wheel lip when, considering that the tire will probably overlap the rim a good .25 - .50 inch leaves for a very fit-and-finish look that I am very pleased with. Please feel free to post any other questions. Oh, before I go, what kit did you order from PST, the super or the regular? How much did it run you? How long did the procedure take? Thanks in advance.
