I send my Pentax equipment to Eric Hendrickson. He is apparently on vacation right now until mid-April, but he does a great job and the cost is reasonable for the quality of work. He has repaired my K1000 and Pentax 6x7 body. He is at pentaxs.com.
This guy works on the 67/6x7 cameras all the time. I think that there are some parts problems with the 67, so you might drop them a note, describe the problems, and see what they say.
I always recommend a shop local to me that does great work. They're fast, reasonably priced, and they work on most anything that's worth fixing, be it digital or analog. And they do mail order:
Pentax USA used to have several in-house factory repair operations plus a number of independent camera repair companies around the US who had a "factory repair" authorization status. I would seek out one of those formerly affiliated repair shops. When I need a CLA on one of my Pentax 67 items, I use their former factory service outlet in Portland, Oregon.

That would be Advance Camera, Inc. it's been years since I was in the shop, but back then they took in my two 67 bodies, each with TTL meter/prism. They did a full CLA and calibrated the meter as required for $150 each. (They miscalibrated one of the meters, exactly one stop off, but redid the job while i waited in about 10 minutes, with much apology.)
