1968 Wiper Blades: @MuuMuu101posted these photos on moparts, but worth reposting here.
There are some differences from '67 blades (shown in an earlier post above). One is the '67 anti-lift foil is longer. So the push button comes through the wing. On his '68 they do not. Assumption here is both the '67 blades above and the '68 blades below are original to the cars.
