An easy way to break the crank bolt loose is to slip a long pipe over the end of a breaker bar and give a quick tap to the starter. Make sure to pad the end of the pipe that will be resting on the edge of the engine compartment. A rolled up blanket should be sufficient. The engine cranks clockwise, so the pipe will rest on the driver's side.
I just had to perform the same service on my car. Taking my time took a couple of evenings. There's still time. Good luck.
Oh; by the way, don't use the flywheel lock while doing the above procedure.
Hope to see you at the drive.
