front bumper question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

prg machine · 05-20-2008, 12:57 AM

I am re finishing , straightening etc. a front bumper from a 9 truck ( no turn signal holes) I am curious about the line along the top edge of these bumpers. Mine had a slight crown just above thelicense plate area. Is this how it should be or is mine bent?
The pictures are kinda hard to tell...... I am refering to the rear edg line just above the center.

Thanks guys

Judging from the front bumpers on trucks that I have looked at there is a very gentle convex shape on the top of the bumper but it is not as defined as yours is. I suspect that you have a "bump" in the middle of your bumper since you can see where it starts on either side of the middle. I would suggest checking the shape by holding it up to the grill if you have the option.

It may be difficult to get the bump back down where it blends in with both sides of the bumper.

That's what I was thinking also. I can manuever it with a hammer and dolly if need be, just thought I'd check here with you guys first befor taking something down that was meant to be.
