Mopowers' 66 Dart Build

I've been gathering up all of interior parts that need to be re-done and calling around to see what a local shop would charge to install a headliner for me. I've received quotes from $350-$450, all the way up to $750-$950 for just the labor. I've heard they are a total pain in the ***, but I may just suck it up and give it a shot myself.
