This weekend I removed the brake shield on my 2003 A$ 1.8T Quattro to replace the brake caliper and ABS sensor cable. In the process I destroyed one bolt holding on the shield (had to drill it out) and somehow lost another. Right now I'm driving around with only one bolt holding the shield on and it's rattling. I can't find any spec on the bolt and would rather not have to go to dealer to identify and overpay if i can replace from local auto parts store. Does anyone know the spec on a replacement bolt?
