I have no Idea where to start

I would get it safe to drive, and see IF you like it!!! I have seen people that just do not like the feel of an old car! Either you will do all the work it needs r you will pay someone. Hopefully you will get the equipment and learn to do it yourself, with in reason. Sometimes just find a friend to help and share his stuff like a mig welder!
Looks like a nice project, much to learn here just reading old threads too. Keep us posted!
Great post.
The very first thing i would do is to get the paperwork sorted out and the car in your name, if you haven't already done so.

Second, (and be completely honest with yourself) what's your budget? (both time and money).

Third, Do a lot of research and reading. Joining here was a very smart move, there is a lot of people on here willing to help as well as a gold mine of info in the threads.
Buying a Factory Service Manual will pay off tenfold in the future.

Other notes:
-Do not expect to make money on the car when you are finished re doing it. Do it as a labor of love, not an investment.
-You'll save a lot of money in the long run by not redoing things.
Example: If you plan to go with big bolt pattern front discs, don't spend any money on the small bolt pattern brakes or suspension, do it all at once.
-Also, i would buy a complete aftermarket air conditioning package instead of using the old one and rebuilding it.
Do this especially if you're going with a big block, it is lighter, more compact, and better all around.
-Do as much of the work as you can yourself. You will save a lot of money and learn a lot along the way.
-Realize that these older cars do not drive like the newer ones that you are used to.
They can be made to steer, brake, and handle like the newer ones, but it is expensive and a lot of work.
-Sell off the parts you don't need to put more money into the car.

Lastly, don't be afraid to ask questions, again, there are a lot of people on here with many years of experience with these cars, (myself included) and we all learn from one another. I learn something new every time i log on.

There's a lot more, but there is a lot of good advice on this thread already.
Good luck, and great to have you aboard.
