I'm almost done revamping these once dilapidated 360Q's but I realized that none of them have washers behind the bolt attaching the yoke to the fixture body. I don't remember one ever being there (I was pretty meticulous about disassembly and reassembly) but I have a couple of 1KL's that have washers here. Should these have them too? Seems like a yes, but I'd like to make sure. By the way, I used Duplicolor 1200 degree engine paint for these lights and I think they look pretty awesome!
