I have been searching for this specific t-molding since I got the Robotron cab....and ended applying the black leather style t-molding a few weeks ago 
I still got the t-molding I removed from the cab, if you need it to repair broken or missing parts, fell free to take it 
Thorsten, I had another look a my cabs and I decided my T-molding is still good enough to keep it.....I feel like hurting the originality of machines more and more by replacing stuff like this.....
Soooooooo, if you still have it, I would like it for sure (hope you didn't ditch it after my initial response).
Patrick: I'm still ordering the T-molding for my Q*bert so I'll order a set for your Ms.Pac too.
