I’m not sure if anyone is still active in thread that could help but here goes:
I bought this 128i with the 135 bumper, the sides connecting to the fenders peak out, past owner said putting the bumper on was a pain so I’m wondering if he did something wrong and it’s something I can fix, it looks like they are screwed in but they peak out

the right side headlight gap also looks slightly high It’s hard to see on picture, any suggestions or other experiences with this swap?
