These were purpose built for the 350GT, they allow the seats to sit at just the right height and position, as its hard to achieve this with the 350 as they have a staggered fitting for the drivers seat. they will take most aftermarket seats, including Recaro, Bride, Cobra etc etc, they include adjustable sliders The passenger side was sold to Paul (Polo) whilst I planned to use the drivers side in another 350gt, this is no longer the case as Ive re trimmed the leather instead Looking for 65 quid delivered
