I squared off about a 6” piece of 2x4 and drilled a 3/4” hole with my Milwaukee bimetallic hole saw after running a pilot hole through with a drilling block to ensure a straight hole. I’m about to attach this piece to the underside of the wheel well and drill through the wood and attach it with wood screws and washers to the two mounting holes. The trick will be centering the block on the existing hole but I’m going to find a something that just fits through the existing hole to center it.
