Right now on Ebay item 4603639550 is right in your backyard, and the bid is like $ 25.00 so far.

Also, my favorite supplier, Jackson Racing Transmissions, has item number 8029695406 with a starting bid of $ 400.00, with no bids so far. Sometimes you can score one of their transmissions for junkyard prices, and their products are terrific. Look at their Ebay rating........2001 replys, 100% rating,

If the guy in Md. is telling the truth, the used one could be a deal, too. Hope these help. By the way, you are looking for a B-O-P (Buick, Olds, Pontiac) bolt pattern, different from Chevy.
