Nice!  That solves to problem of keeping Van's belt setup and mounting 
the unit in a good location. 

It appears to me that a nice bracket can be fabricated that just lays on 
the longerons.  That would ensure alignment and otherwise be simple if a 
bit oversized.  But the rear belts would have to be mounted elsewhere 
(glass top as I understand it).  Or the bracket could be fabricated to 
incorporate the seat belt anchor - but then you have several ferrous 
bolts close to the magnetometer.

Thanks
