If a filter is that hard to get to, why not put in a remote filter mount? I installed one for a friends early 80s GM X Body vehicle back in the late 80s...he was severely handicapped, didn't have a lot of money living on assistance.. and GM couldn't have buried that filter any deeper.. plus it was a shotglass sized filter anyway...
he had room on one side of the engine bay, so he wanted to go extreme to where he didn't have to give the oil much attention yet not worry about it...
so I plumbed in a filter off a Peterbilt for him...
raised his oil capacity from 4 qts to like 10.... filled it with Mobil ONE....
I moved from Seattle back to MN, but I really wonder if he ever changed any of it after I left... ever...
