Secure Shower Arm Brass Fitting

drilling it on the Fly yeah I just didn't think that was the case that's all right and now that is sturdy so before I secure this in place I just want to make sure this is going to work so I just want to hold that right there and I want to make sure because that's pretty much where it's going to go close enough I guess a little more back that'll be fine we can get that squared up but I just want to make sure it looks good in that hole over there
