More OEM Minutia, Carpet Backings Options

In the midst of finally replacing a few key pieces of my original carpeting. Noticed something somewhat strange (see pics). The backing on the driver’s side (on right) is lighter and kind of light, stiff pvc or something. Stamped with “TSB”. Passenger side backing is black and much more rubbery; not stiff at all. Same situation with the NOS pieces I’m preparing to put in and the NOS passenger mat already in (not in pics).

Any experience, insight, or history on this. These are known (mine) original pieces.
As promised, truly minutia.
Thanks!

Wish I could help guys but that lower door trim has had me stumped for awhile.

Early cars were vinyl over pressboard and typically black. Have seen some in vinyl that were in colors matching the interiors and not black. Then at least by mid '74 forward they changed to molded plastic and AFAIK, were always black and not upholstered.

that makes sense.

i must have copped the later ones after they changed how they made them.
about right. late jan 74 car.

thanks again to the voice of authority. (IMG:style_emoticons/default/beerchug.gif) (IMG:style_emoticons/default/beerchug.gif)

probably got a black centre cushion because the dealer threw it into the deal maybe.
and didn't have a brown one lying around handy?
doesn't look out of place in dark brown interior. kind of matches with black handles on doors.
might not have worked so well with a light tan interior?
