Had to remove the existing brass reducer bushing from old AFS probe...it was a smaller hole. Had to root through all my tool boxes to find a 7/8" socket, and of course that was a 1/2" drive and I did not have a 1/2" extension long enough. Keep rooting. Found a 1/2 to 3/8 adapter. All good. Took a 15 minute job and made it an hour!
