Strange Request for Help

[Bluesman123]

This is an odd request and I'm really hoping someone can help me.

 

To make a long story shorter...I am trying to run a 97 5.7L Vortec in a 91 Sonoma. To make everything work, I need to get the computer reflashed with the correct fuel map, shift points, etc. but to do that they need a real VIN from a vehicle with the right RPOs AND I need the service number from the VCM that came with that vehicle (apparently they have to match up somehow).

 

Here's what I need:

VIN from any light duty (1500 series) 1997, 2WD, automatic, 5.7 L Vortec

This can be a C1500 Chevy or GM pickup, Suburban, Tahoe or any of the variations.

 

The VCM service number: The VCM is located (in most models) inside the engine compartment on the driver's side. It is black with black cooling fins clipped in a flat bracket. If you open the hood and stand next to the left front tire facing the engine you can put your hand down on it. It has 4 large connectors and a 5th little one that is on the top of mine although your's could be flipped the other way. On the top of the VCM, on either side of the small 5th connector are 2 strips of bar code. The larger/longer bar code has the SERV.NO. printed on it. This is an 8 digit number. There is a 2nd 8 digit number printed at the bottom of the same sticker...I don't know if that is important but it is so similar to the service number I would like to get that one too in case I got confused when the parts guy explained it to me.

 

These numbers do not need to come from a running vehicle...a junker would be fine so long as it matched the specs and still had the same VCM that it got shipped with. Its the VCM service number that has me stumped. I would just wander around a parking lot until I found the right 1997 truck and copy the VIN through the windshield, but I think they might get a little excited if I start trying to pop hoods!!

 

If you'd rather not post these numbers, please email me. My email address is

Thanks VERY MUCH and have a Happy and Safe New Year!!
