It seems like the converter buyers have become more refined and started purchasing via the "code" (or what appears to be the OEM part number). Does anyone have a good detailed list of the known codes/pricing? There's a bunch of eBooks online that I found, but I don't feel like dusting $99.95 just to find out the guide is awful. I just started scraping cars again, and am going to hoard the cats. I just want to learn a little more about the CAT game.
