after being in the military, and working at a NG Repair depot.. trust me... you wouldn't want true Mil. Spec. parts of any sort..
but i'm sure, if you look long and hard enough., you'll find someone willing to sell you some!

"Mil.Spec." is a MINIMUM requirement standard, and most similar parts are above that minimum.

please explain what a ' 5/16" x 9" bottom bracket bearing' is...

if you meant a 5/16" x 9 caged balls bearing, used primarily in low grade, one piece Ashtabula cranksets......
