One last before and after shot will no doubt convince you that this is a worthwhile repair for the aging Fox Mustangs out there. Above is our driver door with new inner and outer belt weatherstripping and new belt molding. Note how the two belt weatherstrips touch, with the inner overlapping the outer. Now take a look at the yet to be repaired passenger side with ruined belt molding and belt weatherstripping so hard that when the glass is lowered a gap between them remains. For about $185 in parts we had our Mustang looking and functioning better. Of course it might cost a bit more if you need other door parts (panel clips, arm rest pad, and more).
