This weekend I bought a bumper but as so many of them the mounting brackets (the brackets riveted to the inside of the bumper) aren't what they're supposed to be. On one side the bracket is broken and the physical mounting lug is missing. On the other side the mounting lug is still there and the bracket has a small crack in it. So this morning I went to see if the brackets can be bought new. For a moment I thought:"Yey, they are replaceble." but it turned out the brackets are no longer in service

What's the best solution to get the bumper fitted properly. Former owner had it tie-wrapped to his car but I really don't want that for obvious reasons.
The bumper is very tidy, no cracks or big scratches on it so buying another one is not really an option. It's even the correct colour

Does someone has found a good way getting the mounting lugs mounted to the bracket without breaking of again? I've heart of many ppl trying it and failing. They seem to break of every time you try to fix it.
My idea was try to find a knackered bumper where the brackets and lugs are still in one piece but how big is the chance finding something like that? Slim to none
I'll get some piccies of the issue as soon as I have a proper camera. The camera on my phone is crap. I might even put up some piccies of my project if I can find the patience uploading piccies taken over 2 years
