BRABHAM BT REAR WING END PLATES AND WING MIRRORS AND ROLL BAR

I NEED REAR WING END PLATES AND WING MIRRORS AND ROLL BAR FOR A BRABHAM BT50
BOUGHT A SO CALLED SHELF QUEEN AND I ONLY REALISED WHEN IT ARRIVED THAT IT WAS MISSING THESE PARTS. THE SELLER WAS UNHELPFUL. I WOULD BE HAPPY WITH 3D PRINTED PARTS UNTIL I CAN FIND THE ORIGINALS.
MANY THANKS IN ADVANCE FOR ANY HELP YOU ARE ABLE TO GIVE.
