OP: Lots of wisdom here ^^. Not trying to discourage you at all, just wanting you to be sure you know what you're getting into, because there will be times (like yesterday) when you will look at years worth of work, and regret every second of it. If you don't REALLY want to do this, for no reward whatsoever, you're going to be out a lot of money, time, and be discouraged as hell when you get that new dog.
You also are going to find that you have almost ZERO "spare time" with a new baby. What time you have that you think will be quality garage time needs to be quality baby time, if for no other reason than to keep the wife from going bonkers. Also helps set a good foundation for the next 18 years.
Again, not to discourage you, but to get you in the right frame of mind. Be prepared to go months, if not years, without doing anything to your project. One of the parts of major body surgery that sucks is that you can't just go work on it for an hour. Setup and cleanup take that long.
I'm at 7 years and counting on the 67. Rear end has been re-done three times (that farming it out to the body shop plan didn't work out so well for me; if you're going to do that much work, might as well go on and do it all yourself. By the time you finish the rearend, cowl, firewall, etc, you'll be ready to handle the front clip yourself). I moved the car (mid project) two times, and will possibly move it a third time this summer.
You are planning for a major life undertaking. Go into it with both eyes wide open, and understand that there are cheaper, easier, faster ways to get a nice fastback. You should only do this because you want to endure all the pain, headaches, expense, etc, because it's therapeutic in some sort of masochistic way.
