You will have an easier time finding a unicorn than any Saleen edition Recaro or Flofit seats indecent shape.
Go to www.seatsource.com They own Flofit now who made all of the 87-91 seats for Saleen. It was then that they went with Recaro. They sell Recaro too. I know you don't want new, and will settle for a replica, but at least this will help with your search. The worst part is that what makes the seat look so good is the headrests ( the ( net halo ) in the flofits, and the ( net and louvre halo ) headrests in the Recars, neither will you be able to find without buying a Saleen Mustang with them in them.
Good luck.

 

These are always up on ebay. Saleens use Flo-fit seats, same thing I believe:

Right. Good catch. The seller of the seats on that link is Seat Source in Riverside, CA.
The only problem is that the material used for ALL of the Saleen seats is NLA and has not been for some time and the most important part ( the halo net headrests ) NLA also so finding a decent set of FloFits from an actual car in good shape alone is almost impossible.
Like I said earlier, Recaro still makes the exact seat that they sold and made for Saleen in the ealy 90's is also available but not the headrest. Good luck.
