My '79 is equipped with a mild Ford 400ci engine and a new C6 tranny backed by a NP205. The 9-inch in the back has limited slip, while the Dana 44 in the front is open. I have 9 inches of suspension lift, 3 inches of body lift, and 39.5 inch IROK's on 15x12 Weld Typhoon series wheels. I have dual steering stabilizers with front and rear sway bars, and most importantly a confederate flag headliner. I've owned this Bronco for about 3 years, and before I owned it it was just sitting in a guy's yard full of trash on 33's with no lift and hadn't been run in many years. The gearing remains stock, 3.50:1. Future plans include 44's and 5:13 gears, and possibly some new paint and interior work.
