just in case your still interested i just cut the top post to where the posts line up with the old bumper and drilled a hole through the original bumper and the post, then I used some servo screws and screwed the screws through the old bumper into the posts.
Thanks for the answer!
However, I think I found A bumper that looks like it will fit where the old bumper is now

I ordered it and i'll see if I can fit it.
