Password:JDM usually has that stuff, but I don't see it listed. Contact them and see if they can get one for you.

I'll let you know now that they are worthless. I found a set of super-rare rear seats for my '7 and installed them for sh*ts and giggles. I carried a person back there once for my own amusement, but the front passenger had to slide all the way forward to create room for the rear passenger. The guy in back had to lean over sideways too, it's a max height of 4'6" back there. CRX's are just as bad, if not worse.
FWIW, I now keep my 2+2's folded down and covered by the stock 2-seat rear carpet. They're hidden, but still there for emergencys. (OH GOD, WE'RE OUT OF BEEEEEER! :chuckles: )
