This is my '83 headlight assy .
I used UFO 105 mm (plastic lens ) unit to suit my '83 ( D.C repl) headlight housing .
'84 & up Husky use different housing to '83 & have LARGER light ..,.so be sure what housing you have .... & be sure to measure first.
I had to make up 3 small mount tabs to secure lens assy using the 3 screws , (as seen in pic) ,
to housing ( as per original look )
UFO Part No ME 08076 ; (105mm dia lens)
Got it from this place ; (look in electrical / ignition section)

Hope this helps
