When Bendix King bought TruTrak, Bendix seemed to farm out support to Mid Continent. The last time I contacted them regarding a TruTrak servo the contact info was:
Mid Continent at 316-630-0101 (also 800-821-1212), http://mcico.com. Spoke to Bruce, their Trutrak guy.
Tim is correct, MidCo does all support for TruTrak products and stocks the shear screws...and I would venture that they are VERY close to the Dynon, so close that you can likely use them.
