The Stovebolt Site Forums The Shop Area Interiors Seat Backrest Panel Original?

I think that this is the image that I think Brad referred-to?

Jim Carter sells some sort of rear seat panel in three colors (none are now in- stock)
Trim Panel 1947-1955 Brown Attach to Back of Seat and Cover Springs Item #:
UP222BN (Brown)
UP222MR (Maroon)
UP222BK (Black)

That rear cover might not have been used in all Advance-Design years.
