Attack Position 23

Hello All,
Currently I have a 2000 corvette that i purchased and it has a 2008 LS3 6.2L Block with LS6 heads. I went to change the oil for the first time and it had a Auto Xtra oil filter on it. I went down to my local auto parts place and picked up a 2008 filter. Which was a K&N. I get back to put it on the car and the hole is too large. The Auto Xtra filter has a smaller hole. Now according to the book that hangs in the auto parts store The HP-1017 filter should work, as well as the Purolator filter which is PL12222. The purolator didn't work either. I've attached a few pictures below. I measured the opening of both filters and they are different (see below). Are the parts book off at the auto parts store? Or my setup requires a different sized oil filter? I've also included pictures of my oil filter and location. So far only the Auto Xtra filter has worked and the other ones will not work.

Thank you.
