Thanks for the offer, Zickos, but I already ordered some yesterday!
For anyone else interested, I found Gibraltar 10.5mm hinged memory locks
at Lonestar Percussion.
GC and Musician's Friend have the same one
in sizes from 1/2" (12.7mm) up to 1". (come to think of it, Lonestar might have those sizes too, but I didn't check - I just went there because MF didn't have 10.5mm.)
Until they arrive, I'll be using my backup method, which consists of tape and a Sharpie. Just line up the tape and the marks...
