Replacing Altimatic Attitude Indicator with 3-1/8"

[justin hawkins]

Hi all,

My ancient Altimatic II attitude indicator isn't functioning to well and I've got an RC allen unit I'd like to replace it with. As with most, the replacement unit is 3 1/8", looks like the old Altimatic II is about 3 3/4"


Does anyone know a source for an adaptor? I could make one, but would rather save myself the time and end up with something a little better looking.


Thanks!
