Here you go Chief. From a 2AAA. BTW, you made me put down the latest Victoria's Secret catalog to take these measurements for you. /ubbthreads/images/graemlins/wink.gif
Width of flange at front, widest part: 16.25mm
Overall depth, front flange to back of stub: 9.02mm
Width of bulb opening: 3.10mm
Reflector dish depth: 7.05mm
Actual reflector dish width: 13.90mm
Base spread of the 6 reinforcing ribs are the rear of the reflector: about 10.8mm
Taken with a Fowler dig caliper. At least two readings per dimension. There is a small flange around the front of the reflector that actually makes flush contact with the lens. The reinforcing ribs are like the ones at the rear of the 2AA reflector.
