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.

Sounds like you may need to modify the brackets. I looked up the bracket and I would think you just need to drill some new holes in the bracket to line up with frame rails. I would attach the brackets to the bumper like you have it now and mark the spot to drill new holes. From the photos is looks like it fits OK, but I wouldn't want to leave it with just the outside brackets.

Ok I'm a dufus, I had the brackets on the wrong side. Ie. I had the right on the left and vice versa lol. Now I got the inner and outers on. Everything looks good, except it seems like the bumper is right where the tail lights end. Is this ok??

Here is some pictures of the bumper installed correctly with installation tips it should become clear how it all installs.

Notice the brackets are at a down angle.


Notice the holes in the top of the brackets those are for the deflectors.
