Found one of the door skins I needed for my GTX locally on clearance, at Roseville moparts.

I mean, 69 Plymouth, so a very mainstream vehicle line with a high take rate.

Went there and bought it.
If I recall correctly the packaging date was over a year prior to the purchase.
Seems like they should sell more of such a commonly damaged part but maybe demand is lower than alot of us think it is?

I think the best way to drive more part production is backorder anything you need.
They don't know you need it until you order it.
