Dean, I have a 2007 Vue the base plate was installed by pros at Cal Western, in Norwalk, CA. I did read over the instructions many times and you may have overlooked the trimming or sawing of small arears to allow the thing to fit. The guys at Cal Western ar great they might tell you what you need to do. If you can't locate them on the WEB visit itzmeharv@aol.com and Iwill look up the landline number. Harvey
