Here's how to modify your non-cancelling blinkers to make them self-cancelling. (Many thanks to the fine folks at
www.uniquecobra.com for showing me how to do this.)
Prepare the upper steering shaft for removal. You'll need a 1/2" wrench and an Allen wrench.
As you can see, the wheel will need to be removed before the shaft can be removed (the wheel hits the seat). You'll need a 3/8" nut-driver and a phillip's head screwdriver.
Here's what the switch looks like in "neutral". The upper and lower "triggers" are equidistant from the steering shaft.
When the right-hand blinker is engaged, the lower trigger moves towards the shaft. You'll need to install a small "post" on the shaft to hit this trigger.
Mark the shaft at the trigger's location and use a 1/4" drill bit to cut a shallow hole (there's no need to dig all the way to China). Then hammer in a 1/4" roll pin, as shown here. The new pin's location is approximately 1/2" above the existing pin (but please measure your own car to make sure!).
Cut the pin to 3/8" length and chamfer the edges with a file.
Re-install the shaft and you'll no longer look like a dork driving down the road with your left blinker on!
