I don't believe the above numbers will be helpful. Originally Posted by chevy-man77

Was the rear end switch disc to disc or drum to disc (or disc to drum)? If the former, there's no need to swap the combination valve. If you're unsure, perhaps the best bet would be to find a valve you know to be from a rear disc car.
