Is their any reason why I couldnt swap in an F150 TTB axle in place of my current TIB? If I could use the F150s TTB then it would allow me to retain my coil spring suspension and simplify things A LOT. I could just swap the hubs to 8 lug right? The 87 F150 i want to use should be a D44, which is not a whole lot different than the D44HD that came in F250s stock. Im not looking to do any hardcore offroading or huge tires. Maybe slightly oversized tires and some occasional playing in the mud. Whattya think fellas?
