Can anyone help with good info on making sure your body and frame are level and straight while working on pans and fenders, weather its backyard or engineer methoreds. Just trying to keep her perfect as possible. Thanks for all the help in the past too! MOPAR people are the BEST

The method I've used for at home is using a 4ft lever from side to side shimming the rails as needed to level the car side to side, then using a factory frame chart I use 8 jack stands 2 per frame rail so I can set the heights, Finally I measure all the dimensions shown on the frame chart.. I'm attaching a 69 Coronet chart, I suspect it would work for your Charger but a factory shop manual would have the correct one....
