I heard from Jeff this weekend on the Travelall seats (actually, while I was trying to pull the dash off) when he texted me a picture of the top half of the rear seat in progress:
I’m doing mine in gray over black because my dash and door cards are gray, but I’m going for something that looks like this (in tan over gray):
I don’t think the vinyl Jeff got is as marbled as the stuff in the reference photo, but I’m excited about moving the seats forward.
