I've recently acquired an older compound(dads old compound,) and a friend has donated a nice sight and rest to my cause. My problem lays in that I don't have any of the hardware(screws) to mount either of them even though the Darton is tapped for the sight and rest. Does any one know the if there is a "common" thread for this, and if so what it is for the sight, and rest as they are tapped differently? I just want to be able to go by the local hardware store and pick the stuff up(I am set up enough to cut the screws to length I just don't have a set of gauges.) Thanks in advance.
