What was installed prior to wheel well sound Deadener? 71-2 Demon

I am getting close to having the front and rear wheel wells sprayed with the sound deadener/undercoating and wanted to be sure what was all installed on the car prior to this process as I want to have anything that might get overspray/splatter on the car. So I am looking for some original, unrestored cars and/or pictures prior to a car being stripped. The list I have so far...

Gas Tank
Fuel Lines
Brake Lines
Right side exhaust hanger floor pan bracket
Body plugs

some things I'm questioning..

Front bumper brackets
Exhaust tip hangers
Rear brake hose bracket. Attaches to left side floor pan exhaust hanger bracket.
Rear shocks, in the collapsed, up position

Thanks for any help FABO !!
