Just bought a 2002 GTI LE...There are some bolts missing on the exhaust flange to the pipe. What size are they? Also the starter bracket bolt to engine is missing, what size is it. Lastly, the rubber grommet that mounts somewhere on the motor, the bolt or stud whatever it is is gone. Have no idea how to remount the pipe as it was off when I purchased the GTI...pics are helpful as to recounting the pipe..thanks
