* "Mucket" is the term used to refer to each end of the convertible top stowage compartment lid weatherstrip.

The front edge of the stowage lid protector should overhang the stowage lid by approximately 3 mm (0.12 in). That 3 mm (0.12 in) overhang should then firmly contact the bulb seal rear edge of the mucket to complete the seal between the stowage lid and the lower "B" pillar.

1. If moving the lid forward or rearward, a 4 mm (0.16 in) gap between the rear of the stowage lid and the front of the trunk lid must be maintained.
2. Adjust the stowage lid cover downward slightly for more contact. Refer to the illustration above.
