Not that many will want them, even so I have made some.
These fit some early M20's also B31, B32, B33, B34

That is really useful to know, I am about to put a new NEB clutch on my GS type with 600 motor and have been advised that the chainwheels must be perfectly aligned to avoid premature wear on the clutch chainwheel so may need thinner than stock spacer (I have shims to move cush outwards if needed).
