OK Jerry, ever seen those bumper ends tilting down/forward? You probably have....maybe yours does that too... Its not by design ,its from using the bumper jacks...it bends the bumper , or it slides in its elongated boltholes where its attached.. BUT you CAN fix it ... John , "Hammered", gave me good advise on how to fix it.... IF your bumper ends tilt down on the front (most prevalent on 69`s , longer ends) you loosen all the bolts, two at ea end ,and I think it was one under the tail lights plus two at center...jack the car up on a lift, put a 2 x 4 under the end and lower the car again...then tighten the bolts as its straight under the load... I had to do mine twice , PLUS stick a couple of washers as shims under the center ones ,at the gas filler area...
So, as Vikki say ,dont USE the jack, just have for 'show'...I use a floor jack in my garage and have a "fixaflat" in my glove box....
