Dude, those threaded weld washers are awesome. So many uses! I just used one the other day to replace a broken transmission skid nutsert in the frame. Not sure how you feel about using these for that, but it really worked great for it, especially since I had a few laying around. Works much better than welding a nut flush with the frame like I've seen done.
