W/D tow setup

Yeah the problem with my shank is there is not enough adjustment to go the direction I need it to. Most shanks I see have holes all the way up and down, where the hole locations on mine stops prior to the 90 back into the hitch. If there was 1 more hole at that point all would be good. I thought about drilling through myself (I have the tools) but I can only imagine the manufacturer did it this way for a reason.

Here is a picture (albeit not good quality) of this ball positioned at the top. I am 2" lower than the trailer coupling at this location.

Edit: Well I apologize I cannot get the picture to load properly.
