Wind deflectors, as fitted to my 2B. Made from 4mm plexiglass, which can be bent by heating gently with a soft pencil flamed blow torch, along the bend lines, both sides. Keep the torch moving, (if you heat too much in one place it will bubble and burn) and apply gentle force, when soft enough it will bend. If you havn't done this before, try it out on a scrap piece. As Alan has done before, I have used the same type of lift off hinges to fit these in place, I can therefore change from full doors to wind deflectors in seconds. Try to fit these as close to the bodywork as possible, to stop the airflow short cutting to the low pressure behind the windscreen, as this is what causes the turbulance, and bufferting. Don't forget that these are handed, so you will need to bend them in opposite directions to get a pair. I should add thet the tab at the top, is bent forewards to stop the deflectors moving , and should be adjusted to give a snug fit. The bend at the bottom should follow the join above the the side panel.
