I have used AM sets on kits they were not designed of. In fact, I am currently using 7 AM sets designed for a Dragon kit on an old Airfix kit. It often can mean some extra trimming, either of the kit or AM and you have to study the instructions more carefully as the kit part numbers given in the AM sets won't apply.
But doing it with cockpits and things is one thing, doing it with this wing fold set is another. Not sure I would chance it. If the dimensions are off, its going to be a real pain.
I am a Norfolk man and i glory in being so
