Switched to the Mustang Super Touring Deluxe one-piece seat with passenger and driver backrest. So far so great! My only problem is Mustang did include or do they offer a filler / flap (not sure of the name) to cover the gap between the passenger backrest and the seat allowing some of my lighting wires to be exposed... Please share your experience with the Mustang Super Touring Deluxe seat and any recommendations to fill in that gap. Thanks!!
