Where to start on my 63 Dart?

I found one for cheap in a junkyard.
Alright then, I'll call around.

Yes, I've got a very good picture of an early Barracuda with the stock air cleaner and PCV system right here.
Hm, maybe someone did drop a later motor then. My air filter looks more like this one, and looks like it would connect in the same place. http://www.allpar.com/images/mopar/slant-six.jpg

Or, maybe someone just replaced that with a different one. I need to get pictures...

It's not much harder than changing a tire: You unbolt the wheel, pry the center cap off with a screwdriver, remove the cotter pin with a wire cutters, and then remove the big nut in the middle of the spindle. The drum should then come off if you pull on it hard. I'd probably have a machine shop press in a new bearing race. Not particularly hard.
Where would I buy the new bearings and all from? Also, could I put the race in myself? I can't think of any machine shops around here.
