[rotorwrench]

I got a 5-pack from flea-pay when last I needed them. Most of the load-o-matics had some form of clip and all the non-diesel Ford tractors with the conventional type distributor had them up into the 60s. I always keep spares. They are easily dropped or otherwise misplaced when performing ignition work. On the tractor, I usually drop it in the weeds when looking the rotor & cap over.
