I got a tow truck project, perhaps the correct term would be basket case really. It is a 1986 F350 with an 18ft Chevron Aluminum Bed. I bought the truck off of eBAY last summer with a cracked frame, up by the power steering pump. The dude sold it a few times on the site and every time before, somebody would drive/bus/train/plane up and expect to drive it back. It wasn't roadworthy without the frame being fixed, so he refunded the money and sold it again. I was the closest person being within 75 miles that bought it, people came before from New Orleans and further out to get it. So the dude that I bought it from, took some type of saw and cut the cab 6 inches above the bottom of the windshield and the rest of the cab off, so no one would attempt to drive it back. So Yes, it has no roof, back of cab, doors, etc... The front fenders are gone and all I have is the hood over the 6.9L IDI. The truck is a 4 speed manual still and since so much is missing, my friend who towed it home said, why not make it 4WD. So a project began.... I have spare motors for it (just in case), I have a transfer case, Front axle off of a 91F250, and the rear too. I also have a bunch of E4ODs for it. I have a few spare cabs as well in the 92-97 style too! My question is if the original bed ran off the 4 speed with the PTO and I make it automatic, do I need a special E4OD case or is there something after market like an electric over hydraulic set up that people mention yet I can never find? I was planning on going through the axle, transfer case, and tranny anyway before putting it together. So do I need an electric over hydraulic set up, or some special PTO case, or what for it? Yes the bed controls worked fine before the massacre by the previous owner.
