I converted this truck from 2WD to 4WD with the help of junk Bronco. Used the Bronco AOD output shaft and extension housing on the original F-150 2WD transmission. Bronco front axle, front driveshaft, transfer case, and speedo cable were all used. new springs front and rear. 2 in body lift w/ 33X9.5X15 tires. Oh yeah, '89 F-150 manual transmission rear driveshaft(no slip spline on Bronco t-case!)
