The ratchet type I was referring to is on the left. It's much thinner and has a small lever to change directions instead of the cumbersome knob to turn (like the one on the right). This 'lever' type is a lot thinner, and its direction can easily be changed one-handed with the flick of a thumb when b...

My Snap-On 1/4" drive ratchet + socket combo works perfectly in there. It's part of my under seat tool kit. The Snap-On ratchet head is relatively small and its handle is quite thin. It only requires a very small angle of rotation to reach the next 'click' so you can back the bolt out one click...

Your new coil shouldn't be a problem, however, real airhead riders carry a spare ICU.

Depending on their severity and their location, the crack(s) may or may not immediately affect performance. Your bike is 40+ years old, probably still has the original coil. Those coils weren't renowned for instantaneous cold starting, even when new. Consider any visible crack as an unsubtle warning...

While you're at it, check your HT wires with a ohmmeter to be sure they're in spec and that the ends aren't corroded into the coil.

I will be both thrilled and flustered when you turn out to be right! Placing an order now... I'll report back after replacement, for better or worse. Thank you for the input. If I'm wrong I'll give you back every penny you paid me :lol: Either way, a 'real' airhead owner needs a spare coil lying ar...
