Seat is a core but solid rebuildable core for 74 to 80 911. Am I crazy high or is this fair in today's climate? Ive bought a cpl sets of 81 to 84 series but these seem ALOT HARDER to find. In fact I cant find any in last cpl yrs that I can afford so looking for knoledgable current prices. Any recent sales of single seats. If I pay shipping in usa is this out of line? Thx all.
