I thought 2BFlying just did?

FTR, we have the same problem down here as you probably do in RSA, where virtually everything comes from Asia (ARF) is fitted with metric hardware, and worse, 'Chinese metric' which is somehow consistantly different sizing from Taiwanese or Japanese metric.

Come replacement time for clevises etc, it's a PITA as all the Great Planes and DuBro airplane stuff is 2-56, which as 2BFlying just pointed out, is slightly larger than 2mm which means they're an unacceptably loose fit on the existing 2mm 'metal' rods usually fitted to the various dowl control rods or aileron horns. So instead of just being a simple clevis or snap connector replacement, it becomes a complete control linkage including rods swap-over either at the time of initial assembly or at first airframe & control systems overhaul.
