Abstract: A flexible tooling fixture that has a pallet bed lying within an x-y plane and reference elements for alignment of the bed to the manufacturing tool; and at least two sets of supports extending from the top of the pallet bed, each set consisting of: (i) a flexible pivot to accurately locate differing brackets of the sensor assemblies to maintain the axis of the barrel in a common z-x plane, the z-x plane being off-set from the center of the bed, and (ii) one or more fixed stops for engaging the barrel and bracket of each assembly to determine a common-x-y position for each sensor module with the axis of the barrel in a predetermined relation to the bed, one set of supports being located to determine alignment of the axes of one class of sensor assemblies within the predetermined position, and the other set being located to determine alignment of the axes of another class of sensor assemblies within the same predetermined z-x plane when the bed is in a second position that is 180.degree.
