A friend of mine has a 1979 Firebird 400 that has been in a dirt floor garage for the past 10 or so years. There is condensation in the interior, all the tires are flat, the engine needs attention, I know we have our work cut out for us. Most of my experience is with a 1977 MGB so I was hoping for a little direction. Money is a issue but I want to help him to stop the car from deteriorating any further. What should we start with. I want to get the interior aired out and break down the seats and move out any “squatters” (mice)Thanks!
