I'm installing a 350 vortec into my 96 Silverado. It previously had a 305; so I have to get the computer reprogrammed. I need the vin number of a truck with a 342 rear end, stock transmission, and 350 vortec engine. The dealership said they could enter that vin number in and it would program the computer correctly. If anyone knows of a junk yard or any means of finding a vin number for a chevy with those items please help me lol cause i'm haveing a hard time finding a truck like that.

ANY HELP WILL BE APPRECIATED GREATLY!!!
