For sale is a pair of black 1967-1968 kick panels for a coupe or fastback. I ended up with two pairs of these, so I'm selling one.
Ford part numbers on the boxes are C7ZZ-6502344A1A and C7ZZ-652345A1A. Back of the panels are stamped with C8ZB and C8WB engineering numbers. Sold.
Those are C8ZB panels. If you look in the area of the part number stamping it should say C8ZB no holes, C8WB with holes.
Those have no speaker holes pressed in so they are Mustang / Shelby.
