What you will be looking for are actually called West Coast Junior mirrors. GM made them as accessories as did other companies.
her's a kit for Scouts but they should work if you do a little homework first.

http://cgi.ebay.com/ebaymotors/NOS-...LH_DefaultDomain_100?hash=item45ef66d50eI found an nos set on eBay a few years back. They are available from time to time. But you'll find more of the painted NOS sets than you will the chrome or SS ones from GM. Good luck.
