I am new to the forum. We recently traded in our 2007 LR3 for a 2011 LR4. There is no doubt about it the LR4 is quite a change. My question is regarding the LR4 rear tread plate accessory. I have searched and looked on Topix but there is no install directions. I am trying to figure out if this is a DIY install. Has anybody installed the rear stainless bumper tread plate? If so whats involved? Thanks.
