"1970 Pro Touring Dart Build"

I can appreciate the sentiment. Back off and take a breather.
Relax as long as necessary and don't feel bad....smile a little.
Look what you've accomplished so far. The dirty work is largely
done and after you've rested (physically, mentally and financially)
you will feel refreshed and ready to go. It doesn't matter if it
takes a week or a year. Just don't abandon the ship.

Solid advice.
