[Healeys] Locking Crank

[Roger Grace]

Update
Thanks to all for good suggestions.
So opted for the inertia hammer beating method after being able to get an
open ended wrench from Amazon. Did the best I could with a 3lb hammer in
the limited space. Was reassured when Harold found a Churchill tool with a
note that stated no need to "lock the crank" with this tool - so that was
how the factory did it. After about 20 mins of hammering it was as tight as
it could be while still in the car.
