All pro rear bumper

Hey everyone just wondering if anyone could help me with this, I bought a all pro rear bumper used awhile ago and it doesn’t sit how I want it to, I contacted all pro to see if this was correct fitment but they even said it doesn’t look right, there is a 1 inch gap underneath driver tail light and passenger side has a 2 inch. It’s pretty noticeable and I have yet to figure out why I was thinking maybe the bed isn’t aligned, but haven’t checked yet also I put a level on the rear bumper and it’s level not bent.
Thanks

 

I have the Allpro aluminum bumper and it sits a little bit crooked. Also the angle between the bumper and the bedside was a little bit off. I die grindered the holes slightly to fix the angle. I was on a time crunch and didn’t get time to fix the level. I just took the bumper off and put my factory bumper on. My truck is going in for a frame swap and I didn’t want them banging up my nice powdercoated bumper. When I get my truck back, I’m going to die grinder the holes a bit more to align it better.
