One shot here.. but since you were comfortable reworking the gas tank, could you possibly warm the spot where the RothPax is making contact with the hinge and soften it enough so it deflects around the hinge?
Like you, I am looking for a solution to route wires from the tire carrier (Bestop HighRock Oversize Tire Carrier) back into the tub on the hinge side. I am already drilling into the tub to mount the carrier so one more isn't a problem. Just curious what others have done.
I am thinking something like a firewall grommet...

I actually hadn't thought of heating the tank up and trying to rework it. I have a heat gun at work... It is tempting to give that a try. I'm going to think on it.
That grommet is exactly the sort of thing that I was thinking of for routing the wires. For now I ended up wrapping my wires and running them through the gap in the hard top. I'll show it in my next post. I like the way it looks, but I don't know that it will work when I try to put the soft top on.
