Hole Location of Trailer Coupler in Relation to Underside of Top of Coupler

Question

Question:

Could you possibly tell me the hole location from the inside top to the hole center line. I bought item CT-3003-Z and the holes are to far down from the inside of the top so the coupler wont sit flush on top of the trailer tube. The coupler that Im replacing has a dimension of 3/4inch of an inch as shown in enclosed picture.

I went and pulled a Trailer Coupler 2" Ball 3" Channel Tongue # DL13800 from our warehouse to get the dimension you requested and the distance from the underside of the coupler to the center of the holes on the side of the coupler measures 3/4 inches.

This is the same as the picture you submitted which I have attaches as well.
