This truck has a 7.3 non turbo charged diesel out of a 1990 truck.It has an Allison AT545 automatic transmissionStarted building a flatbed on it. Used heavy materials 3" & 4" channel for the frame work.Has gooseneck ball, nverted king pin and has the rails for a Reese 5th wheel hitch.Also a receiver hitch on the back. There is more money in the material for the flatbed than the beginning no reserve price.It ran when parked. Only reason I quit driving was the wiring harness under the hood shorted out and melted together. I know nothing about auto electrics.
