Hey mate,
i got 2 ke70 xx edition grey front seats in my garage. They don't have any rails on them but you could just swap some rails you may already have and they should be all good to go. Good condition seats with swabs underneath still in tact, the only down side is 1 cigarette burn in the passenger seat. $40 for both
Pm if your keen and want to check them out.
Cheers Tom
