AC Delco EGR Part Numbers Confusion

[Axle]

Every manufacturer seems to change part numbers for no apparent reason. I've gotten more than my fair share of "old stock" that has a few different part numbers either stuck on it, or hand written with the original or previous part number crossed out.

Jeff, if you get an oppertunity, just page through an aftermarket emmsions product catalog. While the manufacturer will have designated part numbers for various revisions or calibrations, the aftermarket has one part number that covers all models. (Ford IAC and EGR valves for instance, ford has umpteem different model numbers depending on the ecm calibration code, but the aftermarket has... ONE to cover all similarily equipped engines). Some time spent at the BWD online catalog may reveal similar results, it'll just take a lot longer than a print catalog does to look up various applications.

As for your egr, if it fits, use it. It is not that critical at all. It either opens, or it doesn't. =-)
