Coincidentally, I have exactly the same cabinet with the Twin Cobra conversion. I replaced one of the sticks with a Dominux to use during the testing phase. I don't recall if I needed to enlarge the holes slightly to get a better fit onto the existing studs, but I suspect that would be the most you might need to do for that metal panel. Just use sticks which use the traditional "American" mounting pattern, and you should be ok.
Sticks in that category from our catalog include:
Dominux
OMNI2
Pac-Pro
Super-Pro
Competition
