adapter for pentax >smc< to digital?

I have a few Pentax Super Multi Coated Takumar lenses that i use on a Spotmatic F.

They do NOT fit properly on a regular M42->NEX adapter. Both adapters I have use a flat ring behind the mount to press the aperture pin. The tabs on the lens prevent them from screwing completely onto the adapter, because they bump against the ring in the adapter.

Are there any other brands that will allow these lenses to be properly mounted?
