Total Noobs

Okay, so my boys inherited a couple cars. 72 and 75 Darts. They belonged to their uncle who had them for many years and just never had the time to fix them up, and he recently passed away.

So the first question. The youngest son recently bought an Olds as well. It was recommended on a forum to get an assembly manual, a service manual, and a Fisher body manual. The first two we were able to download and the last came in the mail yesterday. The question is, what are the equivalent books that we should have for the two Darts?
