What you need to know
Identify side and exact leak/noise path with water/air testing. Check frameless-glass indexing/alignment, gusset, door adjustment and seal damage before ordering. Do not confuse roof-side, door and body weatherstrips.
OEM numbers
Checked Subaru roof-side upper weatherstrip 63521CA000 right and 63521CA010 left. Front-door/body weatherstrips, gussets and glass run/channel parts are separate.Supersession
No left/right supersession exists. Toyota badge cross-references must be confirmed in the Toyota VIN catalog; the Subaru side numbers are not generalized to every seal around the door.
Fitment
Identify side and exact leak/noise path with water/air testing. Check frameless-glass indexing/alignment, gusset, door adjustment and seal damage before ordering. Do not confuse roof-side, door and body weatherstrips.
Aftermarket options
New OEM and used original seal paths were checked. Used rubber needs close inspection for compression set, tears, deformation and donor storage damage.
Before you buy
Right and left are different. Confirm whether the fault is the roof-side seal, door/body seal, gusset or glass indexing/alignment. One checked catalog path was explicitly unavailable; used rubber condition varies.
