Well, I'm not allergic to some oil on the garage floor. OTOH, I wonder if it might be possible to eliminate the case leaks by cleaning really well and bolting together with silicone adhesive. That wasn't widely used or available in the '60s and '70s. Corning even makes a variety now that doesn't contain acetic acid (no vinegar smell) and won't corrode metals. It's expensive, but its sealing properties are somewhat better than the Home Depot variety.
Thanks for the info on parts. Not sure how much of the up-front work I would do myself, just wanna be sure I'm not gettin' into one of those swapmeet-only situations just by buying something like this. I swore off those vehicles (and swore at 'em and on 'em) about 20 years ago.
