Sunroof rattle repair advice

[E38flagship]

Hey guys having an issue with my sunroof , it has been covered by a few people on here by adding electrical tape around the "lets call it the track" on the front sunroof. The issue I'm having is my track is broken apart and sitting on bare metal apposed to it sitting on plastic before I found a "repair kit" but it also includes the cables is the track now made of metal ? I can't tell from the pix, should I just purchase this kit or is there something else I can do to repair it?
