I currently purchase the Aries Step Bars for my Murano and I am having a really hard time installing them. The instructions are not all that good. Basically, i know I have to put the 1st bracket on the tow in the front, but I cant find where the L-bracket should be hooked up. None of the wholes have threading to hold the bolt. I talked to the guy and he says to put it on the brace for the engine, and there is an existing bolt there to replace. Anyone tried to install? any clues would be great!
