My thanks to everyone for your help regarding the turn signal mechanism for the '68. Having the parts numbers is a time-saver when visiting the parts counter. New questions: 1. What style ignition key was used for 1968? Was it the square-headed kind used in '67, or the pentastar head used both earlier and later? 2. Where can I buy 18 inch Anco windshield wiper blades with the original-style airfloils? Dave Duricy
