Regarding "
-if you have to remove the bracket put the old sensor back in and tape a 8 mm washer on the end of it. Then bolt the bracket back in. The washer will make sure that the new sensor is at the correct spacing.
-Pull the old sensor back out and put the new ones back in.
Also if you do a search there is a thread with pictures showing you how to do it. "
Ok, I need to pull the bracket, can someone direct me to the pics on the 8mm washer trick mentioned ?
