We just got back, I forgot the camera. I would have liked to show pictures of this. It '' WAS '' a 1/4'' or maybe a 5/16'' hole. But it was not 3/8, I know some of you think this is not possible....but I have no reason to BS anyone.
I just drilled it with a 9/16'' drill bit and tapped it with a 3/8'' NPT tap.
NOW, it is 3/8'' and the fitting is in place.
Thanks for the help!!!
