05 door linings vs 07 door linings
 

What's the deal with this? They have different part numbers.
Does anyone know if anything actually changed? Looking to replace my 2005 door linings and they are discontinued.

2004 - 2005: 83580-S2A-A61ZB
2006 - 2009: 83580-S2A-A63ZB

Good question. Combed through my reference pics of each year's interior (yes, I have reference pics lol) and there's no obvious difference cosmetically. Even the padded leather inserts *look* the same, though I only have a true close-up image of an '06-'07. The door nets and tweeter housings appear to be identical. (Of course if you're replacing both panels, then cosmetic details won't matter to you.)

If there are any non-cosmetic differences, I'm guessing they'd be on the inner side of the panels, probably to accommodate revisions to the wiring harnesses when drive-by-wire/VSA was introduced. But the only wiring that's actually integrated into the panels is for the door locks and windows, and those should (presumably?) be the same, i.e. same connectors/pins, etc.

I'm sure someone here has done an interior swap and might be able to say for sure whether there's anything about the '06-'09 panels that's not plug-and-play.

Thank you. I know they appear identical on the outside, been comparing via google images lol. Just hoping the tabs arent moved or anything. I doubt it though.

The S2000 shop was saying the inserts were different but I think they just confused my question with AP2 vs AP1 door linings, plus their english isnt the best as theyre in Japan. Most things I find online mention AP2 inserts in general, not AP2v1 and AP2v2.

I pulled the trigger from Majestic. I'll update here when I get them. Hoping it's an easy swap without any modifications.
