Replacement keepers type

Yesterday I got the TIII head back from the machine shop and had just finished installing the new valve seals. Got 6 of the intake and 6 of the exhaust springs back in place. The first few were a real pita but it got easier as I went along, figuring out how to slide the keepers in a little more effectively. Anyway, on the second to last intake valve I managed to send first one, then a second keeper flying across the shop and possibly under the milling machine, but not sure. Question is, if I can’t find them, are the TIII keepers the same as T1 or T2? Or other applications? Not sure on where to source them if need be.

thanks
