This is a very helpful item..this is new in the package set of (1 left, 1 right) ignition contact points for the 1963, 1964, 1965, 1966 and 1967 Triumph. This will fit the Triumph Tiger and Bonneville, Trophy, Daytona, Tiger Cub, Thunderbird etc. These are correct for the following bikes: T120, T100 ss, TR6, T20, GT Thunderbird, Correct replacement for Lucas Part # is: 54415803. Single cylinder bikes only need 1 of these..but you still get 2 in this purchase. If your beast is running a little rough, putting in a set of new points and doing your timing works wonders!! I have run these in my own bikes for years now. I like to give the points surface a quick polish and then clean with carb or electrical cleaner for great long lasting running and timing of the point/ bike. Let me know if you have any questions. Great deal! We only sell the best!.
