looking for passenger side Cab and chassis axle

looking for passenger side Cab and chassis axle.. had the junkyard look for a C&C rear for me and they did but when i picked it up someone had already snagged the passenger side axle... So i call the GMC dealer and ask them and they need a vin# to do anything. its for an 87 crewcab it was in a dump body truck. anway someone has a vin i could use to get the part or a part # or just an axle????

thanks for any help.

just call an aftermarket axle company and get a set. They really don't cost that much.
