This is a fresh core tear down from an 87 F150. This is a 4wd case and the transmission was worn but not in failure yet. Case lugs are good. Threads are good. The only defect I see is the top starter bolt hole has been heli-coiled. I’ve show in the pictures that a starter bolts up and holds good although the threads are not completely parallel to the surface. Still works fine. No returns. Please ask all questions before purchasing.
