Every LWB A/T I have seen had it. They do bolt right up on the SWBs v6s. One of the brackets is welded to the LWB. You can custom build the bracket or drill out the one on the LWB. Mine was being held in place with zip ties.

Frank, I have an oil cooler from a 91LWB on my flooded out Raider. Im not sure about water in it, I dont have the truck from NO yet. I plan on parting the Raider. PM me if interested.
