I've got a complete 190k motor w/#22 stamp and orig. trans(core) sittin on my garage floor - purred like a kitty before I janked it. A few months later went and scooped up a complete 86 SDL with the intention of scavenging el transmisione. BUT I'll be a monkey's unkle, that dern SDL turned out to be a gem, so now I change my mind daily bout which to keep and which to sell. Hrrrmmmm
I realize this don't help your sitch, but I'm thinkin daily, or as frequently as you poss can, trips to the yard is odds on your best play. Next would be combin craigs. Just this last week alone I've come across two SDLs, complete and both under 1500 asking. One came with a cracked head
and can't remember what the other's deal breaker for me was. I seem to remember something like logistics killin it. Just gotta watch. Stay diligent man, they come around.
You scour fleebay yet?
