ZHP gloss blk outer window trim-came loose

The window trim at the rear driver side has pulled loose on my car.
(2004 ZHP 300i)
It is piece 13 in the Exterior Trim / Grill diagram from the realoem site.

I have tried gluing the clips twice now using a two part epoxy -- but they don't seem to stick well.

Has anyone else had this happen and found a good solution.

That piece of trim alone, in Gloss black for a ZHP, is listed at over $400 on the realoem site -- my extended warranty does not cover it -- per the dealer.
I can only imagine what the dealer would charge to replace it.

thx
Dale

no 14 on diagram = 89.93 USD described as Glanzschwarz (gloss black) whereas, the non ZHP part is 28.71 USD i know this is two years too late but if someone comes along later and reads this, hopefully it helps... there is a small screw at the bottom on the inside if anyone is replacing or removing this piece be careful not to pull the window gasket apart as you remove it, and be sure to put it in all the way or it could jam you back window as it goes up. if you do that you shouldn't need a new window regulator like i did.
good luck to anyone who tries this... it's less of a crisis, more of a bother, really.
