You running the new version now, or the one you started the thread with?FWIW if I'm running the 90 degree adapter I remove the adapter and oil filter
as a unit working from above and pull them both up and out (after first disconnecting the high tension lead to the distributor and pushing the wire out of the way for more room). Installation also from above. Only possible disadvantage is the O-ring for the adapter gets a bit flattened so might have to replace that O-ring more often (?every filter change).
