okay on page 2 step #2 The directions say to install a washer after road testing if a condition occurs. Just wondering if anybody actually installed all that stuff only to rip it all out again to put a washer in, or did u just put the washer in the first time. Or do we not need the washer. Also I cant find a .107 drill bit, I have a .109, What size is the one they included. Thanx.
