I'm haveing quiet the hard time tracking down truss heads in M6, let alone with 20-30mm threaded lengths. Do any of you who have fashioned cants have a source? Seems very few are imported into the US. I found a source in MD, but I would need to order 1000 of them. Ouch.
If you haven't used truss heads, what have you used that both supported the universal disc and sat low enough to not obstruct the slider?
