I've never used any after market bumper on an e39 but anytime I've seen pictures of them fitted, they seem too short where they meet the wing. As in they don't line up with the wheel arch. You might find pictures of this if you search online. I would keep searching for an OEM one even if it needs repairing.

I've bought plenty of parts off mcg, very good to deal with and helpful if you give them a call.
