hey Guys,
Im just adding my 2 cents here: I put a 1988 C1500 rear
end under my 50 AD. Used the stock springs,hangers,and shock mounts and moved the spring saddles and shock mounts on the rear end. The stock 88 Chevy PU wheels with 255/70R 15 tires fit perfectly and line up just inside the running boards. The set up looks great especially since I didn't want to use deep dish positive offset wheels. So your rear end list doesn't need to stop at 1987,
fyi, Bill
