Yep, my measurements were on target and the 12mm fit like a glove. Sears had one but only the key style so I will order a 1/2" drive socket for when I put the wheel back on.
Signed up for the 28th today too... gotta fess up to the wife and probably leave a little early since we have plans in Boston that night.
It will be worth it. LOL!
Thanks all!
Dave
