Ok, so Im reading and just realized the 747-16 retainers from Comp are for a double spring?? BUT the 901's are singles?? Their current catalog/pdf recommend retainer #'s 730, 740,743,744,1730 NOT 747...GRRRRRR. They have been running "fine" in 273 for 5 years now.....
Here is a pic I took in 2012 when Badsport shipped to us.
