Which of the two holes in the side panel are to be used for the front radius arm mounting? There used to be a note on that in the Guide. It depends: Watts linkage? Road or track use or both?Also, the left hand rear mount of the a-frame seems to have been welded on slightly wonky, such that I can't get a socket onto the nut. Is this something I could try and twist to re-align, or might I require a new a-frame? Can you add a photo of it on a flat surface? Jonathan
