I have no Idea where to start

Everyone has given me great advice so far. I really appreciate. I want to make sure the safety stuff is good so I'll be te as ring things down to suspension this weekend and working my way up. It has carpet but not molded carpet, it's like someone grabbed a roll and threw it in. Yes it's the one in Oklahoma, owner was Ace. I agree about the aftermarket A/C set ups, I had just seen that when I read the post. I'm not sure if I missed it or not from a response but how specific are service manuals? Does it legitimately have to be 1968 Dodge Dart GT or are the manuals for a "family" of cars?

a. You don't have to tear it down to check the suspension. Pretty much all the testing can be done while its together.
b. Seats and carpet come out pretty easy. You can put the seats back in without carpet - there's no wires to step on.
c. You can get either a Dodge or Plymouth Factory Service Manual for 1968. There's no further breakdown for regular production cars.
1. If something doesn't make sense, look for a TSB. The 1970 Hamtramck Registry Library Page (1965 - 1969)
2. If you need tech guidance, see what Master Tech had to say: Master Technician Service Conference - Chrysler's Training for Mechanics
If you want to see factory sales and advert literature, look through Hamtramck historical website, at least to start.
