For comparison's sake, and since I'm bored and happen to have it sitting in my living room, here's the specs for the AKG mount. Used roughly 2K miles.
Bolt end to end = 110.44mm
Mount top to bottom = 69.06mm
Top thickness = 60.32mm
Bottom thickness = 89.27mm
Weight with included hardware= 1 lb 4.1oz / 570g
Subtract 1 oz / 28g for hardware
