When ordering a new Cobra Trailer from an authorized dealer:
are the insides specific to a particular glider or merely specific
to the size of glider - i.e 15 meter, 18 meter, Single Seat, 2-place.
Or are the rails and wing storage brackets specific to a particular
Make and Model?

There are a lot of parts which may be specific to a certain model.
Some gliders require different tops (especially older bigger-chord
or big-fin models). Some 18-meter gliders fit in a 15-meter trailer
with removable tips. Anyway, your dealer can help you.

Happy to help you with Antares-specific options !
