What you see is what was my rear muffler bracket being used to mount the FASS pump. I installed stacks on my truck so the bracket was no longer needed. I cut it down and then used 4" long 5/16" bolts to mount it "upside down" on the driver side frame rail. I had to re tap the threads on the bracket to 5/16" since I could not find metric 4" long bolts to go all the way through the frame. It is plenty sturdy and puts the pumps ports in the proper position. Its also pretty quiet in operation.
