This morning I was able to contact someone at GM that after much looking was able to come up with GM # 9436790. He couldn't find a "trade" number for it. So I then checked with a local dealer and they didn't have it and also couldn't come up with a trade number. So they checked with one of their suppliers (AC Delco?) and located it. They come from GM in a package of 10. So to get just one a dealer must buy a package of 10. At over $5.00 each, most dealers are reluctant to keep such a rare, low selling bulb on their shelves. This dealer should have it in a few hours. Price to me is $5.83. Hope it's the right one. Will update this posting with results.

Thanks for your help.
