is it possible to put back seats in an '85 ???

 

To the best of my knowledge, rear seats were an option in all JDM RX-7s, even if they weren't in USDM RX-7s of the same year.

I'd start by e-mailing the guys at www.fdnewbie.com and asking if they can score you some seats.

 

Yes, thre is such a thing as a back seat for your car. I had a back seat in my 79 Rx7. Bought them from a company called Pacific in the early to mid 1980's. It was the same company that used to sell the glass moonroofs, not sure if they are still around.
