That's one nice Nova! Nice job with the repairs and engine bay clean up too. Dig in and go for it. You have a great foundation to work with there and like 67rstbkt said, if you cut it down into smaller projects or sections it is really not too bad. Go look at what I have to start with and you will feel MUCH better about yours.
I am having a hell of a time with motivation this week and no idea why. But looking around here and asking questions seems to help get me back in gear.
Good luck and please keep the pictures and updates coming. I just subscribed to this build.
