Well, you've certainly found the right place! Like you, I'm restoring a Mac 22 (78 model) and I've found the folks at this website to be extremely knowledgeable and willing to help new owners get their project into the water. Couldn't be doing what I'm doing without them. :dance:
Congratulations on your most excellent acquisition! Isn't this the same year / model as in the book FIX IT AND SAIL? (My copy's down in the car, it's night, raining, and I'm not going to go check right this moment.) If not, it's almost the same. If you don't have the book, and nobody's recommended it yet, you might want to get a copy for reference. I found it very informative, and a lot of fun to read at work when the boss isn't looking.
Good luck with your project, and to echo what's already been said: TAKE LOTS OF PICTURES!
It's getting near Christmas and I'm working straight through, so if I don't get back here before then, we wish you all a happy and safe Holiday Season.
VBR,
Pat
