1050	Rearrange stripline buckle & lower heat-sink. Previously the lower heat-sink and the buckle were attached together to the upper surface of the ring at the bottom of the IVC middle-section. Now the buckle is attached by itself to the top surface, and the heat-sink bracket is attached to the bottom surface. This lowers the top of the buckle so that it is more comfortably clear of the bottom of the 100mK can. Now even if the can is tilted all the way to the side it won't touch the buckle (it would touch the striplines if tilted very severely). See photos:
