Sounds like a complete rotisserie re-do to me....
This is how Rudy's Camaro started --- and then with all the work just to get it torn down -- you start with the "well... as long as we're here we might as well do....."
Ya know what - 16 months later - it's worked out just fine. We've fixed everything that was ever wrong with the car... so he's going to have a real decent car now.
