69 barracuda front bumper bracket question

Hi all, I'm trying to install the front bumper today and found that the inside leg of both bracket do not line up with the bolt hole on the bumper, there is like 1½"off on both inner bracket
PN on the bracket 2768584, 2768585
Is there other part number involved to these brackets .
Thank you in advance
I think the people on here that can help you need a little more info... what company made those brackets? Original frame rails and bumper? Photos? I have a '69 that I could compare photos to yours.
