NOS Lucas Left and Right Hand Controls Norton MK3 Triumph T160 - these are almost impossible to source.  The left hand control is correct for the 1975 Norton MK3, the right control has bullet ends as used on the later Triumph 160?. You will need to change connection end if you want it for a 1975 MK3. Original NOS Lucas see pictures for details. You'll need to click on the second one to see it ( formatting issue - sorry )

$625 for the pair - pick up in Newmarket or can ship for cost ( once Canada Post strike ends ) with etransfer
