lazs is right........1966 IS a good year.
Those are my favorite Chevelles and El Caminos. Reading this makes me wanna go back and get my '66 Elky up and running again.
Bought it in 1983, got it running and drove it a while, but it's sat idle since 1985. Gonna need a lot of work to get it roadworthy again, but it will be worth it..............
