Sorry, there are variations here I know nothing about. Guess I got lucky.
The advantage of the Fuji Quick Changers I have is they are a lot newer than my old Graphmatics which I had to fix and they have more wheels you can use to identify the particular holder along with the sheet number. Really nice to easily find the exact sheet matching your field notes when you're making small changes in exposure or filtration as when trying a new film and the duplicate exposures are almost Identical. Might be worth getting/modifying a spring back that accepts these if this Is important to you.
Otherwise might as well just carry 3 double sheet holders, hopefully edge notch coded providing sheet numbering. And edge notches do not intrude into image area like the Graphmatic type holders!
Good luck.
