83 GLX 5.0 5sp. I noticed this as I was removing stuff in the engine bay. Right in front of the strut towers on both sides there is a small inward bow on the frame rails. The only noticeable damage to the front of the car is the lower radiator support. 10 years in a bodyshop tells me the bows are not supposed to be there. The only reason I am questioning this is because they are there on both sides.
