Replacing the carpet in my 1986 GT Convertible. I have the charcoal grey interior (code PA). Looking at LMR the list they correct carpet color as Light Grey and reference ACC code 852. Looking at the ACC website, they list the correct interior carpet color as Medium Grey code 857. I ordered samples of both and the Medium Grey 857 seems a lot closer than the Light Grey 852 that LMR is selling. Which color codes have others used when doing this job?

Thanks,
Tom
