68 Charger interior rear window trim

I know this has been discussed many times, but has anyone had good luck finding a decent set of the plastic interior rear window trim? The set I purchased from Classic Industries does not fit well and will not stay in place.
How about feedback from others that had the same problem? How did you make it work?

i had to bend that metal strip it slides over in varying slight opposite directions to help give it some resistance and used spray adhesive sprayed into a paint can top and applied it with a small hobby paint brush looks good and stays in place. my original was discinigrated by the sun except for the center piece that clips on and hides the seam, good thing because when i put that part on the C.I. part snapped in half. the original popped right on. still has not had much ride time but has stayed in place for over a year and seems stable. so watch out for that center piece its not very flexible.
