I'am also building a US60. The Hanger 9 Retact Gear you found will fit nicely in the wing. The JR Sport retact servo RT88 is about $25 here in the great white north. The retacts seem well designed, and the spring load struts with trailing link are heavey duty, so for about $70 a wing I should have a nice retact setup. Just make sure you follow MinnFlyers suggestion & move the retacts out one bay. Heres a couple of picks of my trail retact setup.
