Advice on storing Cobra in Milwaukee

[Engineer Ed]

OK, I've recently moved from Tampa, FL to Milwaukee, WI.
Basically I've lived my entire life in the Sunshine state except for a 6 year stint in Germany with the US Army.

I'm getting ready to put my Cobra away for the winter and wanted some advice on an effective, yet easy means of storage.

I plan to store the Cobra in my 23' trailer.
In brief, here are the steps I plan to take to "winterize" her.
Please offer your advice if I need to make changes.

1. Remove race mixture and add fresh coolant.
2. Fill gas tank
3. Add Sta-Bil
4. Drive car a few miles to mix Sta-Bil with gas.
5. Air up tires to 40psi.
6. Load car in trailer.
7. Turn off fuel pump and run fuel out of carburetor
8. Remove air cleaner and coil wire.
9. Spray generous amounts of WD40 into carburetor and turn engine over to pull fumes into cylinders.
10. Reinstall air cleaner and pull battery (store inside fully charged / battery tender).

Any thoughts or suggestions?
I'm assuming she will sit for 5-6 months or until after the spring thaw?
I plan to change the oil before taking her out for the first time....
