What is the distance that the swinging pick up has to to be from the bottom of the pan? I have the milodon 31151 oil pan. I ask because I was using it like that but in this build I notice it sits kind of high. I measured it and when it goes to one side it measures 3/4 and when it goes to the other side its 7/8. I am worried it's too high. Do they sell a swing pick up or the block that makes the arm sit lower?
