the idea is to catch the spray oil and not foam it < directional screens work the best for this they trap it like a bee hive would -- the new scraper design has an added benefit it comes with an oil pan with a side pocket that runs full length of the oil pan at a downward angle twards the rear so all thrown oil directional from the crank can in a liquid form ( not bubbles and soap looking stuff ) end up at the pumps intake -- the old side scrapers did not do that they instead bulked the oil up at the gasket edge and i always felt foamed it a bit and in extreme cases leaned out the volume that is supposed to be thrown into the piston skirt area < the company's that sell this stuff know nothing X wall mart workers at best sooo you are on your own with the distance you choose to the crank the scraper ends up -- to close it may oil lean the pistons to far away and its a paper weight my suggest for what its worth is a canton oil pan company's windage tray and mod it to fit your combo knowing a 1/3 rd might have to be trimmed to use -- jz
