In this video I pull the original Ford 9 inch out and replace it with a Ford Explorer 8.8 rear end with disc brakes, 3.73, and limited slip. I also install a Backyard Customz (BYC) mini c-notch kit in the bumpside F100. I run into some trouble at the end with the offset of the wheels not clearing the bed.
