Pablo,
Looks like you and Gcernie have the same RA setup with hardware.? Questions for you both, by tightening the black Allen screw on the top plate you're only locking in the Allen bolt (chrome color).
Second question, where the chrome Allen bolt screws into the RA worm block, does the hole on the RA Plate allow up and down movement of the RA worm block (so you could pivot the worm block to either side of the RA ring.? Are those holes oval like shaped?
