73 Duster -- Father-Son Project

My Dad bought this 73 Duster a few weeks back, October 27th I think.
My Dad had a 75 Duster when he was a little older than me, which played a big part in choosing the Duster.
He's a truck driver so he's only home on the weekends, when he's able to get home. I'm in college, so I'll be working on small stuff when I can.

Anyways, we went and picked it up that day. Unfortunately, I didn't take any pictures before we started. My Dad took some, but they're on film. I think by about Thursday 11/1, I had gutted just about everything from the interior. The week after that, my Dad was only home for a few hours, so we took out the front and rear windows and some other small stuff. He wasn't home the week after that.
We got a da sander 2 weeks ago and started taking down the surface rust on the roof. That damn rust is a pain in the ***. On top that, we've got a small compressor. Dad wasn't able to get home the week after we got the sander, and I didn't do anything on the car. I've been sanding on the rust a few days this week, and we got fairly deep this weekend with it.
I found a little tutorial on getting rid of surface rust with naval jelly here: http://www.hotrodders.com/forum/secrets-surface-rust-removal-revealed-55679.html I figured we should try it since the naval jelly's only $7.

We plan on getting and rebuilding a 360 or 340, not sure yet, just depends on what we come across. Most likely going to be using the 727, I mentioned to my Dad about using the 904, but we're not sure on that either. One of my Dad's brothers works at Jeep Masters and he's very knowledgeable of rear ends, and he offered to rebuild and help with our Duster. My Dad's brother also knows a guy who is very experienced with transmissions, so we might get his help on rebuilding the transmission.

It'll be a slow build, but it'll be fun.
