I found the right bulbs. I got the hoopty all registered and inspected today, to my surprise. They didn't like my windshield wipers so I had them replace them and I beat the labor cost out of them. $12 each; I figured I'll pay that at the store anyway.

Now I have the oil, filter and coolant to change. I'll start a new thread on the coolant because I read a few threads on it and there were about as many different suggestions as there were posts!
