3phase,
It's cool of you to take the responsibility because you didn't check the parts when you bought the kit. However, most GK makers are helpful when it comes to replacing parts. I know the ones I have dealt with, at least. I would give the kit maker a try to get correct parts. I haven't dug into my Kettenkrad in a while but I don't remember any of the tracks looking like the resin ones you have. Give it a shot, man.
EDIT: I forgot that there are tracks like that on the wings!
