When I got the free 1966 bug it had a dash under tray fitted .Its made of wood & has a ally trim to it with VW in the center .It fits with a simple
clip so Simon you could even make it .its held to the side with a adjusting screw .
& its been cut out & made to the rear fire wall size .
I have it out the car if some one would like to trace around it to make one .
Looks very smart in there .
