installing new bumper....please help!!!!

[1972BlueC20]

Hey guys!

I really need some help urgently. I'm installing a new sport bumper on my 72 c20 LWB today replacing an old aftermarket step bumper. I can't seem to get the inner brackets to line up with any of the holes in my frame without the brackets sticking too far out. I heard you can just use the outer brackets as long as you don't plan on stepping on the bumper. So I got the 2 outer brackets onto the frame using the outermost holes and I got the brackets attached to the bumper. It's holding itself up now but I'm not sure on the way it's sitting. I don't know what's normal. Does this look right fitment wise??? Any help is greatly appreciated. I really need to get this done today. Classic parts gave me the bracket set they said would fit, but I'm having trouble with the inner brackets. Maybe I got the wrong brackets? Idk.
