Yeah I need the special plate nut that slides in the rails to the hole where you put the bolt through. I have bolts with the right thread, however without the plate the nut would spin freely. Only other option would be to have a plate drilled and bolt welded to it, then pray I the bolt never breaks off the plate....
What is the difference between the 1'st and 2nd generation plate nuts? Would I be able to buy the extra set you have from you?
Hmm, I just thought of an idea... I could have a plate cut to the right size to fit in, and just the right size of the nut, then I would not have to worry about a weld breaking. However I think this will cost me dearly to have 2 made for me....
