To anyone who has done this, did you use the rubber "gasket" between the projector and the reflector? I bought the tool to tighten the lock rings with and I've tightened it to the point where I'm scared to go much more and the projector can still be wiggled a little bit so I'm nervous that they'll move after hitting bumps in the road. They seemed to be more sturdy without the seal but I still fear that one big bump and it'll move and then the nut will be loose.
I didn't grind down the lip on the reflector side of the hole because it doesn't look like the reflector is even on all sides so I wondered if that would cause problems also or weaken the plastic too much. I gound down the back lip completely so there was a good flat surface for the retainer and lock ring. I thought about taking the seal out and putting epoxy or something to attach the projector to the reflector another way once I get the beam level but if that doesn't work there'll be a huge mess left behind.
