Leaf makes this cool - AFi/Hy6 to Graflok adapter plate which can be then fit to any LF camera that accepts standard film holders or film backs. The great thing about this adapter from Leaf is that infinity focus is retained without adjustment - so if you have a rangefinder or stops that are calibrated for film this is a direct swap. I use mine in my Polaroid 110B conversions and Linhof Technika's. It's fun and you can get different looks, plus movements.
These cost approximately $750 but about the same price as alternatives, but does get to infinity focus whereas the other's don't thanks to the turning locking mechanism on the inside face - shown in the first image. I can order them for you or you can also get them from your Leaf Dealer.
