Well I have seen them, even new, to where it almost looks like the hole is the shape of a cross...kinda has the appearence of edges sticking into the hole/daylight..

I`m not sure what size wire you`d need to shove through..but at best, I`ve been abel to get the tip of a needle just barely into the hole, i do that from both ends..not alot, as you may ream it out, and ya also have to be carefull not to break off the needle tip in it..
