It appears that I have 2 front bumpers. Since I am building a driver and not a show truck, I decided to make a couple of spacers for the bumper on the rear. It worked out just fine, and looks OK to me. The 2 outside bolts worked out fine "as is". I made 1-1/4 in. spacers out of wood for the 2 inner bolts. If the painted wood doesn't hold up, I'll make future spacers out of something else. But, for now, I'm good to go.
