[Richard/Ca]

The way I did it was to put a peice of wire through the d-nut bend it(I made a little ball of wire) so it will hold the d-nut in place after you get it through the hole. It will take some manuvering to get the d-nut through the hole I had to tap with small hammer. After that I just pulled up tight in place and sodier it in place being careful not to get sodier in the threads. Cilp the wire and that is all you will have inside the channel.
