Is there a way that I can research GM parts on-line?
I am looking for parts swaps between different GM Vehicles, generally body
An example is I would like to compare if there is a different part number
for the forward door weatherstrip between a GMC Envoy and a Buick Ranier
Most counterguys get really po'd if you try to get them to do it. Surely
there is a way one can access the GM parts info?
