I have a seriously nice set of original '68 sportseats and bases - unfortunately, they're the wrong color for my '68. They would look great in my '67, though. Question - if I redo the pads in Pepita, and cover the headrest receivers, will these be more or less identical to the '67 seats? I really don't want to change these unless they'll work in this fashion - it would be better to sell them otherwise.
