I have a 1995 6BT from a DRW UPS delivery van in my conversion. The van my engine came out of was burned so the insurance company probably sold it to the salvage yard. The guy I got it from said it definitely was a UPS truck because he saw it before the engine was pulled, but I never personally saw the truck. I checked the engine serial number on Cummins QuickServe and it was for a Ford chassis.
