I am currectly awaiting Phil Bleazeys Centa Conversion Kit. I have done the prep work already. As Phil say, "ypu can get two fingers in there to work on it."
I can get my whole hand (the hand is small) into the hole and it is not as long as what Bleazey cut but I just could not understand why a longer hole was necessary. Maybe omeone can enlighten me before I reinstall the unit.
