Glad you have it sorted out, I missed the rubber band thing too. Usually threw them away. I believe in 76 they had a larger single piston caliper. It's susposed to be a upgrade for the 73 to 75 caliper and I'm told it's a direct bolt on. I think you'll enjoy the feel of the disks once they "bed themselves"..I takes a short time to mate the new pads to the rotors.
