Bob,
Sorry, I can't remember what airplane you have.

I'm wondering if your A&P had to trim the instrument holes of the panel to
get them fitted properly. I recently talked with a mechanic that was
installing them in a C206 and he had to trim the instrument holes slightly
to fit them. His comment to me was "if they tell you these things just pop
right in, tell them they're nuts!" When he was finished, the install looked
great, but he showed me how they held the instruments back too far unless he
trimmed the holes.

We had to trim them all in the Mooney. The instruments are very close
together and would have hit each other if we did not trim.
