I pulled the rear seat (seat bottom and seat back) out of my '76 300D when I parted it out a decade or more ago.
They have been stored in my living room, nice and dry and non smoking so all ready for planting into a 115 chassis (this is for a sedan).
I guess pictures are possible but being dark now and they are black a decent image will be hard to obtain. I may try to get photos tomorrow.
I prefer a local buyer anyhow so come take a look I am sure you won't be disappointed, no tears or splits and the material is still supple.
Shipping could also be possible if buyer will pay for the materials to wrap and package for UPS, truck or? Located in the SF Bay area and can deliver within 60 miles or so.
I think a fair value considering the condition would be $80.
PM if interested.
