.....I opted to change compass styles and go for one mounted on the dash. I did move the vent starboard a few inches so everything sat plumb. That was no issue as I had the black vinyl dash up and front windscreen out. ....
I had a windshield strap-mounted vertical card compass in my 180.
Wanted to move it to an empty hole in the panel to clean things up.
Tried several location on the panel,
couldn't find one where it didn't get jiggy when you turned on the master, radios, lights etc.
And each electrical switch changed the jigginess.
In the process, I over-adjusted it and stripped the screws or something so adjustments didn't do anything anymore.
So I bought a whiskey compass, tried mounting it lower than before on the windshield strap--
again, to clean things up a little.
Looked great, but now it blocked my view out the front.
I ended up with it right where the vertical compass had been, several hours of monkeying around and about $100 later.
