I think those are hi lift mounts. As for the swamped; it looks virgin.
I had to use separate lights between the brakes and the blinkers. I had the same issue you are having when I did mine. My thoughts at the time where to wire them kinda like a trailer but I couldn't make it work.I have room on each side of the red lights for some clevis mounts. Those should bee here next week.
I have the wiring almost figured out. Only problem is when I try to use my blinkers, both of the red lights flash no matter which direction I signal. Any suggestions? I'm sure its an easy fix just don't know where to go from there. I plugged into the stock harness with 2 female plugs off of some smashed up tail light housings that I had laying around.
