Need advice on what style under-seat tool tray is original & correct for the late 30 straight w/s (68-B) Cabriolet with adjustable seat carriage. My tray was replaced with plywood. The original tray would have had 4 horizontal flanges screwed vertically into rabbets in the wooden side and cross rails. Approx. build date of your 68-B and tray style would be helpful to me. I also need help in finding a nice original or repro tray. I asked this question on the Cabriolet message board hosted by Bob Johnson but no responses after nearly two weeks; not much traffic on that message board, but tons of great info on Bob’s main site. Thanks to anyone who can help solve my tool tray puzzle.
