Other Auto Repair Sites?

Anyone know of any good ones for advice/discussion? I have an '84 Toyota pickup that I use for hauling stuff. The engine is getting pretty old & tired (has something over 200K miles on it), and might not pass its smog test this time around. The air injection pump seized up last time I drove it, and who knows what else might be wrong.

Anyway, I don't want to fork out major bucks for a new truck that I'd drive only a couple thousand miles per year, so I'm looking for advice. Any suggestions where to start looking?

Thanks,
