To clarify: the crankset is already drilled. The chainring is what I have to custom drill, unless I want to hold out (and fork up) for a Merz chainring.

I found a freewheel with all the right sprockets that I thought was Ultra spaced, but I discovered it wasn't. It's also unfortunately a Perfect, and I don't think I can use the sprockets (or just the R21 that I need) on a NW freewheel. I don't think Perfect 6 speeds can be respaced to Ultra 6 spacing?
