Identify left/right and outer versus inner molding. Inspect clips, door glass bushings/adjustment and rust; replacing the beltline does not repair a top-to-glass leak.
OEM numbers
Checked outer beltline molding NA01-58-810F passenger/right and NA01-59-810F driver/left, with earlier E revisions shown in collision catalogs.Supersession
Earlier E -> current F revision is supported for the checked outer moldings. It does not combine left/right or supersede inner belt, door, top or quarter-window seals.
Fitment
Identify left/right and outer versus inner molding. Inspect clips, door glass bushings/adjustment and rust; replacing the beltline does not repair a top-to-glass leak.
Aftermarket options
OEM individual sides, aftermarket pairs and condition-checked used moldings exist. Clip contents vary and must be checked.
Before you buy
Left and right outer moldings differ. Do not confuse outer beltline, inner belt, full door weatherstrip or convertible-top seals. Check clips and glass adjustment before blaming the molding for every leak/noise.
