Welcome to the site Adam. You've come to the right place for all your A Body needs. As far as that `67 Notch, just make sure you check all the problem spots. Check the frame rails for rust through, especially at the torsion bar anchors and rear spring forward perch's. Nasty bits to try & repair. The inner fenders/ firewall rust out too. I searched your zip code in your profile and I see you live in my favorite place on Earth: San Diego. If your car is a local, forget the rust issues! The `67's have a few unique items that are one year only: gas tanks...idler arms...windshield mouldings. Nothing to scare you away though. Otherwise, just use some common sense. Try and buy the most complete car you can find. Trim items can cost a small fortune. If your not already a member, look up the Mopar Club of San Diego. The last time me & my wife we're out your way we crashed one of their meetings (Held at a Mexican resturant...) and found a ton of great people! I was wearing my Mopar Power Club of Long Island, N.Y. T-shirt and they freaked that I found them! (Actually, my wife found their web site and told me they were going to have they're meeting while we were out there!) A good support group helps ease the pain of searching for parts, as I'm SURE you know all about owning an AMC product!
Let us know how you make out with the `67 and please post pictures of your Javelin. I always thought those were cool cars!
