As they say in the rag trade, 'Suits you, Sir". As for oil filter clearance, I've used the Z37 oil filter on my L18 Sunny for exactly the same reason. They match up to the diameter of the opening nicely & the O-ring sits in the middle of the landing. The right angle bend is from the Bluebird & is removable & probably can be retrofitted to the L16. You'll soon be cruising the coast, just in time for Winter.
