Woody, I had a pair of these on my 51 in 2006 At AACA show and was to show asked to show documents witch I could not show so points were taken off. I now have a copy of a sales brochure but still not sure if this will be ok for AACA or was this what they would say was dealer accessory and points still lost. If any body has any information if these are ok with AACA now please no. You have to drill eight holes for each side so before I drill into my new running boards I like to find out.
