I have a 70 Dart with Dr. Diff front disc kit 5X4.5 (Small ball joints adapters) and 8 3/4 5X4.5 Axles, with Dr. Diff rear disc kit, The springs are in stock location. I am looking at these wheels. They are 17X8 with a 5.25" backspace. That is the only backspace they offer for that wheel style. Will that backspace clear the front and rear?
