02 or 03 Chevy Silverado 2500 dedicated CNG part needed

[gnclow]

I am looking for an Alternative Fuel Management computer made by impco. I can’t find a part number for it, but this picture has some identifying numbers on it. This computer lives on the passenger side of the truck between the front bumper and wheel well. Thank you for any help finding my part or a whole vehicle that has been retired or is sitting at a wrecking yard!
