Mike, Nice find! Looks to be very solid car. Good call on new tank. As for the bumpers "appear to have been over torqued", I believe there should be odd looking larger type washers between the bumper and mounting brackets that sort of give a bit of spring cushion when the nuts are tightened to prevent distortion on the visible side. Often times people will not bother to acquire new ones, or clean up and paint the old ones, in their excitement to install their new bumpers. Tip: when I install a new bumper (especially the rear) I scuff the inside, clean off residues with a pre-cleaner or lacquer thinner, tape off where the bolt holes are from the outside and undercoat or use a bed liner paint to protect it. The inside that you don't see is typically where all the road debris from the wheels hits and the rust begins. Good luck with your car, nice!
