Here's a pair of very nice 1960 Buick taillights, with a spare included (bottom of the photo). These are about as good as you'll find, unless you find a stash of NOS parts. The spare isn't bad, but has hairline cracks in the lens and a dent on the chrome bezel. I bought these when I couldn't find any '59's. Now I found the '59's, so have no need for these. These also look great on a 1955 or 1956 Ford, if you're into mild customs. $100 plus the ride, which should be around $20 to most places on the mainland.
