Davey Do -
Wow, that is indeed the same mounting system as mine. All the same parts! I tried playing with those brackets every which-way but couldn't figure out how it had been mounted. My memory didn't allow me to remember that it was mounted higher than I remembered...you picture and drawing brought it all back.
Wonder what the history is of that particular mounting setup. It isn't referenced in the nicely researched oil filter article on this site.
Thanks a lot...
