Ok I have the timing right and it seems to run good, but the distributor is not where I want it. I rotated the housing 1/8 turn clockwise and moved all wires back 1 position. The vacuum advance is pointing toward the passenger seat/firewall. How can I keep timing where I want it at 16 and get it to point toward the passenger side without running into the oil pressure sending unit?

Looking down in the hole for the distributor is the distributor drive that has a slot in the middle of a gear. I'm assuming this is what I will need to reposition get things where I would like? ? How do I do this without messing things up? Not sure how it's all put together here so I want to be sure what I'm supposed to do first before I try.
