That flat bolt on bar or plate is about 4 inches long, hole to hole is about 3-1/2, is really hard to measure on bike! Sounds like that plate did not come with guard? That one to me would be the last one to bolt on, so you would have some wiggle room to play with. I cheated a little when I installed that piece, took that plate and where the frame bolt has to be backed out, ( also have to loosen exuast, did not have crush gasket to replace it with ), took a metal cutting wheel and cut out a notch to just drop over that bolt. Made install a breese!
