Hey Sonny...my led's are a bit similar to yours and i had a head scratcher trying to figure what i would do for "stalks" for the rear.
I dismantled the original rear stalks and inside the chrome bit is a rubber stalk. After quite alot of deliberation, i cut those rubbers and used them to extend the lights out far enuff to clear every thing. I had some steel "L" shaped brackets which i bolted under the guard and attached the stalks and wiring to them.
