Is there anyone that knows if an Blanik L13 open trailer will work for an L23?

If you add a holder for the horizontal stabilizer it should work if it's like the open L-13 trailers I've seen. If the open trailer supports the wing leading edge with a saddle down opposite the inner edge of the aileron everything else should work OK (we have an L-23 trailer in which the wings are supported by fittings that wrap around the tips and that is one area in which the 13 and 23 differ quite a bit) When we put an L-13 on the open L-23 trailer we had we had to make the wing leading edge saddles sit higher so the L-13 "tip-tanks" cleared the floor of the trailer but once that single mod was done it could take both 13's and 23's.
