Twin Jimmys, yes those are the parts.
klhansen, I am talking about the bottom of the channel, I beleive the flag end was formed from the parent material of the part, not welded on. I like the idea of just JBWelding a piece onto the one I can not get a standard J-nut to work on. The JBWeld would only need to hold it for assembly and if anyone ever tried to take it apart down the road.
I am pretty sure regardless of how I get this together it will out live me but buying new may be the best route as the existing channels have seen better days.
