Well you may never get them,,

Consider how ARFs are produced, they make "production runs", if EF has enough demand for that color scheme plane they may order a new "run" of those,, at that time they'll likely order extra parts. But no ARF company is going to order just a couple sets of wheel pants from a producer, it would just be too expensive.

You're better off getting the right size from a Great Planes ARF or Fiberglass Specialties that's in stock and paint it to match,,, you could be waiting for ever

good luck
