I think, that landing gear must fit, because that is two absolutely same models.
In center fuselage section must be made changes, because Airworlds landing gears are in one section tighten on wooden part which come from front to rear side.
I have some other drawings of F 104 scale landing gears, but from smaller scale.
Must find time and ask my friend Martin to made drawings of all parts, increase all and finally change area in fuselage around landing gears.
That is complex process, but can be made.
This construction first must be made in 3D program...
