I assembled air intake door 6-B-20-50 to frame -20-52, mounted hingles 6-B-20-51 and -20-59. Mounted 6-B-20-57 under control panel frame, and bracket 6-B-29-60 to angle. Than connect lever with UC0410 screw-washer and oocknut to door. AN3-4 bolt, double washers and locknut. A little tricky to find right position for lever on right side, hard to make it stay open. Continue with installing 4 mm rivnuts at center consol angles and angles under control panel.
