1987 R20 Chevy Silverado 3+3 Started life as a 2 wheel drive. It's now 4x4. I used a doner 1985 k20 for all the parts. Lots of time into this conversation. Truck runs and drives nice. 6.5 none turbo goodwrench diesel engine. Sm465 trany. 6 inch lift. 35s. 4.10 gears. Interior is decent shape. Everything works exept cruise ans AC. Driver side fuel tank leaks. I just run the passenger. Some cab corner rust. Overall clean truck for the age.
