I ran across an ad on Craigslist for a '66 GMC with factory bucket seats.
http://oklahomacity.craigslist.org/cto/2640772220.html The ad claims the seats and matching vinyl padded door panels are original equipment. I was skeptical, but then found an article on oldride.com (
http://www.oldride.com/library/1966_gmc_1500.html) that says "Also available are bucket seats, padded dash, carpeting, padded door trim and custom sports interior." Looks like a rare truck but I don't think it's worth half the asking price. Has anyone seen or heard of this option before?
