Ok for anyone who cares... here is what I did... I took some scrap metal laying around maybe 6 inches long by 4 inches across trimmed it up bent it to a 90 and drilled a large whole in on side, covered it in heavy 4inch electrical tape (just in case) and inserted a grommet... in the gromet want a bolt and on the top side of the bolt attached the 3 1awg cable...

This will attached an existing bolt whole near where the battery was on the frame rail/shock tower... all seem to work fairly well so far... I will have picture later if anyone is interested...
