Another useful bit of info I've found realating to this dbase. If you goto
AdvanceAutoParts and you can punch in the same model number in their part# search, just leave out the hyphen, ex 2-199 would be 2199. this will give a few hits, you want the Fedco product. This is really nice for those of us with local stores, but the rest of you can order from that page. Also the local shops don't stock all the cores, but they can have most of them the next day for pickup.
peace.
