looking for a full set of 89-91 GXE leather seats in black. no rips/tears. Im in NY and also in Boston. Willing to swap my whole cloth seat set (in excellent clean condition) for your leather seat set + compensation -OR- just buy the leather covers. thx

not the best pic, but you get the idea

 

I don't have em, but I encountered a few on car-part.com as I was browsing. They mainly deal with cars that are permanently parked, but it's a good resource if no one wants to let go of their stuff.
