The Dugan pieces look nice I think they are around $169. I am designing my own plates right now that will be made from Alum, it will go from the shock tower to the head light on the drivers side, The Passenger side piece will cover my K&N filter and that area. I am going to mount my MSD on the plate where the battery was since it has been relocated to the trunk. I was able to re-rout some of the wires on tht side into the inner fender and I re-routed the wiring harness from the top of the shock towers to the sides, it really cleaned things up a lot.
