Door panel material differences throughout the years

gshort24

I have light beige seats that I hate, and suede door inserts in my 2009. I want to upgrade to black racing seats, and find some black suede door trim panels/ inserts off of e-bay, but the descriptions, and pictures on e-bay are never that great. If I can find a good driver side door panel from one year, and a passenger side from some other year, do I have to worry about the stitching in the suede insert being a different color or thickness etc. or is every door panel with black suede going to match regardless of the production year or 370z version type it came off off?
