Probably don't is the simple answer. ABS is designed for a specific vehicle. A lot of money is spent tuning for that specific truck. You can't retrofit and expect it to perform. I have wondered if an '88ish rear ABS only system might could be made to work, but I would not try it. You would have to have that axle to get the sensor and on and on. The only way that might be safe would be a chassis swap and keep everything-even then you are not going to have the same weight balance as the original vehicle.
