The 93 - Let me know what else I can do. If you get real serious, I can go back over there (it's not far at all, my parents live a couple of miles from there) and bring a tarp and really give it the once over. I'll crawl underneath and check/poke the nooks and crannies for rust and what not. The trans just behind the motor on the 93 is oily. Doesn't really look like rear main, more like leaky rear valve cover.
Basically it looked pretty good for the money.
