external oiling questions

One bad-*** wedge right there! One feature of the swinging pickup I'am a bit sceptical of is the 11/2" square inlet screen. With that big snap ring securing it. The math says not to good. My static pickup has easily at least 5× the screened area. Still use both systems to match the pan/application. I have seen swinging pickups with a large wedge shaped foot before. Much larger inlet screen. Anybody know where to find one?
