180mm M42 Voigtlander maximum focus short of infinity.

I have a nice 180 Voigtlander APO that will not focus to infinity wide open. At f8 I can just get by. I have a cheap adapter that Is just about perfect with a 27.46mm flange measurement. I have tried to reduce the internal spacer on the adapter about .15mm but it is not enough and I don't think I can get much more.

1. Has anyone ever removed the mount and removed internal shims on a lens like this? Is this a risky thing to do?

2. Is there an M42/ SontE adapter that can be adjusted to a flange distance .5 - 1.0mm less than spec?

3. Is there a Voigtlander repair shop that can look at my lens for a reasonable price?

Thanks for any help or advise.
