Call and tell them u want the new front pivot shaft and bolts. This allows you to use the stock front mount holes under the hood for the skid. Simplifies installation. As for the rear mounts, I made my own out of 2"x3" plate for each side. Drilled holes in the plate. Used the rear skid mounting location on the tunnel to bolt the plate on and drill for m10 mount location, which is just in front of stock mount hole and bolted it up. Did this on both sleds. Simple and fast and have never had to do a retighten of any bolts.
