Hey all - installing a single ARB roller-drawer into the back of the 80...was thinking this was a simple bolt in using the existing 3rd row holes (where the locking plates are), however that only appears to be the case for the forward mounting location while the instructions indicated drilling is required for the aft-most mounting location? The instructions are a little confusing as well since it seems to indicate that drilling is only necessary for 5-seat models but then the diagram and directions go on to say drill a 10mm hole to install the rear “B” mounts for both 5 & 7-seat models. Posted wording & diagram below, just want to confirm before I start drilling...Thanks all!
