I did a quick look in the online catalog at
http://www.rockauto.comThey show a few choices, if you do not have cornering lights. Based on that, I'd say it will be available to you locally.

You would be surprised what can be obtained for your old car through your local auto parts store. It might be special order (takes a few days to get in) but a lot of things are available and not too expensive.
You should get to know your local parts guys. Try different stores until you find a good one. Deal with the same ones over and over. When you do, they will take the time to dig into the books to look for parts for you, or call their main office. It helps to go in with part numbers. Do some research online before you go. I get a lot of stuff this way.
