This is unusual.

“This was a VW diesel swap project I have been working on. GM Saginaw power steering conversion. Has painless switch panel. New tires. It is registered, It runs and drives. I unfortunatly underestimated the little diesels power for highway speeds when i chose the gear ratio. Take over this project or I may pull engine to part it out. I still have all the hardware to install a small block Chevy. It has disc brake upgrades large rear brakes. Dana 27 Front, Dana 44 rear. 4.27 gears, Detroit Locker rear. Dana 18 transfer case SM465 Chevrolet truck transmission with Granny gear. I will separate the diesel and sell if interested in the jeep only. Or sell whole thing.”
