My jeep is a 1972 Wagoneer with a 2 barrel motocraft carb. The transmission is a GM TH-400. The transfer case is a Dana 20. Front axle is a dana 30, the rear is a dana 44. I have a spring over lift which provides about 5" lift for 33x12.50x15 Wildcat mud tires on 15x8 rims. I have plans to move the rear springs directly under the frame with buggy springs.
