Front bumper help please

[Jdlawrence1]

I have a 1980 Chevy silverado. I have purchased a front bumper off a 83-86 Chevy pickup. I have seen many of these style bumpers on the 73-80 trucks. The problem I ran into is that it seems to hit both fenders where the newer bumper wraps around the sides. This won't allow me to get it close enough to attach the bumper to any brackets. Does anyone know how to make this work? Does the bumper need to be modified? Any help would be greatly appreciated.
