Oddly enough, I just got done replacing mine a few hours ago. Lot of work, but was pretty straightforward. Yellocoyote's instructions were awesome and a big help (thanks BTW!). Jeep stealership quoted me $1500-1800 dollars to replace it, but $800 of that was for the rack

; only cost me $230 bucks and 6 hours of my time to do it myself. As to answer the specifics of your question, I have no idea. I replaced mine because the dam mount broke.
