Right angle filter adaptor

Yes that does help Thanks. Does it slip all the way up the bolt right up against the adapter? What does it do? Also when I was looking at the adapter kits I saw some with the plate that goes up against the block and some without. I thought the plate was for the straight filter adapter. I guess my question is, is there a plate that goes between the right angle adapter and the block or does the right angle adapter mount directly to the block with no plate at all?
