Is this a good buy

It's hardly ever the rear main. I vote valve covers 100%. You should've seen mine prior to my reseal

I say buy it. Replace the valve covers, TB, LBJs and call it good.

Looks like it needs a lot of TLC but if I were being honest I'd buy it in a masochistic way for that price. "Could be fun" I say.
