parts shall be inter-
changeable with all other like units.  Jigs and gages shall

provided by the contractor
for use, where necessary to insure such interchangeability.
3.4 Conformance with Drawings and Specifications.- All component parts shall.be in
strict conformity with the applicabl e approved drawings and material specifications listed
