I am looking to replace the headliner in my 2014 981S researching it I found this part 981-555-091-14-2WO (Genuine Porsche 981-555-091-14-2W0 |Headliner | FREE Shipping on Most Orders $499+ OEMG! | GetPorscheSilverSpringParts) MSRP 1293.92 says if fits 2016,2017,2020 Cayman. I also found this 982-867-501-C-2W0 (Genuine Porsche 982-867-501-C-2W0 |Headliner | FREE Shipping on Most Orders $499+ OEMG! | GetPorscheSilverSpringParts)for MSRP 745.43 Fits 2018-2023 Cayman. So if they both fit a 2020 Cayman that according to the first part fits 981 why not just buy the 2nd part and save over 500 bucks? It also says that the GT4 headliner will not fit my 2014 why?
