Recover rear seat back cheap??? coupe same as sedan?

[spugeddy]

I have a 85 300 cd (coupe) and was wondering about the rear seat back.

Question 1 - Is it the same as a sedan seat back?

Question 2 - Would it be feasible to buy a used seat back and try to replace it myself? And by feasilbe, I mean cheap and relatively easy.
With Palimino, would it be obiviously a different shade..... depending on sun exposure, etc...

Question 3 - Anyone have a decent MB Tex Palamino seat back covering...
