It's happened on the driver's side on my car...I'm shopping around for a welder guy to fix it. As far as it being cheap? Seems to me around my area, $100 is what it'll take to weld and reinforce it properly.
I fived mine bu cutting some heavy guage steel from a F150 bumper, flattened it out, drilled a hole in the middle of it and welded it on. smoothed it flush, right before the paint job. doesnt cost much, just need no know someon who welds.
94 V8 on 17" custom paint, R.I.P
97 Mark VIII LSC yeah
08 Ford Edge, white for now
I just fixed my driver door one in autobody class. The best way is weld it up from the front. make sure you replace the door hinge pins for a good repair. my teacher said the sagging door hinges causes the strikers to tear the metal over time.
