HELP! New Motor rear main seal Leaks

It is hard to see with my eyes which are getting a little bit creaky here. Heh heh

The damed HOA here bitches at me about my rear mainseal leak, so instead of putting a new one in with the engine still in the car, I just bought a 1991 360 to rebuild in the back shed.

Why spend $14 for a seal on a tired old 318 when I can instead build myself a new 360 for thousands more? (With some six and half year old help?)

Oh God don't get me started, I HAAATE HOA's!! Our neighborhood doesn't allow non-running vehicles to be parked outside even if it's in your own driveway. I'm living in my parents' house though so it wasn't my choice to live in an HOA community lol. I made a promise to myself the first house I buy will be with no HOA on a big lot where I can park all manner of old vehicles, running or otherwise. I'll give up being close to everything if it means I can make my property look however the hell I want.
