The 463 gets what the 463 wants, and this time around it was new Recaro seating. I did some seat time in these seats in a friends Syncro Westfalia and I always thought they might work well in a G-wagen.
They're the LXF specialists with grey leather and the arista cloth insert. They came with the recaro sliders that are not even close to what an early 463 has for seat tracks.
I made some adapters that bolt to the factory pedestal and allow the use of the factory Recaro tracks. Pretty easy really, the only hard part was getting the seats centered so the recline knob clears the inside door pillar. I have a pair of arm rests coming for the seats, they were back ordered.
