I know not the usual crowd for OEM parts, but posting here just in case. Local to the Austin/Dallas/Houston area (literally in the middle of all 3).
Got tons of OEM interiors bits and bobs if anyone needs to replace something. All prices are starting points. - interior door panels ($150 each), window regulators ($50 each), windows with 15% ceramic tint ($100 each), passenger knee airbag w/ full glove box ($200), both curtain air bags ($200 each), and a headliner ($250). Few more feel free to ask.
I also have the rear shelf, rear plastic trim with cut outs for the Watson bar, and OEM oil pan that was used for 4 hours of run time. Holler if you have any questions!
Is the OEM oil pan baffled? I am thinking it is an upgrade on my 2016 GT PP.
