bumper problem

Okay...this has been a work in progress (approximately 4 weeks in the making). I have recently replaced my passenger headlight and in the process discovered that my vehicle must have been in a previous wreck. Reason: 1. Paint job done poorly (overspray underneath left headlight assembly) 2. Poor body work as indicated by missing bumper bolts (which was the reason for the slightly loose bumper) along with one of the bumper bracket bolts severely bent and stripped. As a result of this, when I try to use a replacement bumper bracket bolt it acts as if it fits and then...it slips and is loose all over again...i.e.--stripped bumper bracket. Alas, here is the question, can I replace the bumper bracket and if so can I or do I need to order a new bumper bracket bolt? Second question, how hard is this going to be...do I need to have a body shop do this for me? Thanks for any help as I really need it...and I really want to get back to driving my car. Thanks again.

I would suspect that you can have a body shop fill in the stipped metal and you can retap it

Thanks Yeu...I really needed some help with which direction to take with this problem. Didn't know really what to do. Thanks again.
