I parted out a 74 W100 a few years ago and all I have left is the front axle and don't have a need for it. For those that don't know 72-74 1/2 ton pickups used the larger bolt pattern, 5 on 5.5 and are very hard to find now. This bolt pattern showed back up starting in 80 on 4x4s and 85 on 2wds. The front is a basic Dana 44 but with lockouts and the (nowadays) rare drum brakes. Gear ratio is 3.54, $300.
