Well I looked at mine and see two locking capscrews and two pointers. These are on the side as well as the mounting brackets. These were angle once but I beat out the upper section to conform to the base below the RT table. I drilled and threaded for two 5/16X18 bolts at each side which angles are bolted to the Tee slots. The old dovetail base surface is clamped flat without actually touching it but it is the register.
Insofar pix; I never posted one here. It will happen soon as I have many of interest or it won't.
