Finished up the fabrication and mounts. Ended up using #6 Rivnuts compressed into the ends of aluminum tubing to be used as mounting posts for stacking the Magnetometers. Pretty pleased with the results. They are mounted to within 1/10 of a degree accuracy using a Digital level. The callout is for 1 degree accurate. Well, it may be overkill to be 1/10 of a degree accurate, but I could do so -- and I did. Note: Rivnuts were used for mounting and construction as these are not a magnetic material such as a nutplate would be. So, there's no interference with the Magnetometers in this location. Holding a wet compass near or around the units do not react whatsoever. Good to go!
