I am presuming that you too, like the rest of us with a Pre-OBD II diagnostics are doomed to a "Test Only" Station.
About all you can do without a "sniffer" is to have a clean air filter, vacuum and PCV systems are working as they should, your gas tank cap has a good seal (yes they test that too) and it is properly tuned.
Good Luck. It sounds like you keep your truck up real well.

That, and make sure your truck is fully warmed up when you arrive for the testing. If your truck has that charcoal canister for fuel tank vapor routing back to the carb, make sure it is hooked back up as well.
You'll probably be fine. Don't worry too much.
