Anyone restoring a T3 Single Cab pickup is pretty spoilt at the moment.
Outer Sill panels, and the filler panel between the B Pillar and Side locker are available. Along with the Side locker for the Left side at least!
Other panels are available too inlcuding the panels with the louvres above the rear arches. When we say "price on application" for those, you know they're not cheap!
Other panels are sensible for perfect fit Genuine VW Pressings though!
