Moser Engineering - Part # 7750 - Big Ford New Style/Torino Housing Ends - Housing Ends - Assorted Parts
This should be the one you need for the Explorer brakes. Check with Moser to be sure. If you use these housing ends you should have enough extra material on your short side so that you don't have to add anything, that is if you measure and cut right the frirst time. These ends will work with 3 or 3.125 tubes. They also work with other sizes as long as your welding skills are up to it.
