Stupid ass me I got them on Ebay but then after I got on the boards more, I found them at Browns Diesel for 415.00 shipped. I purchased a Sinister EGR Delete and a new HPOP and STC pedestal and new Black Onyx head gaskets. So, hopefully I should be ready to go and to have this thing bulletproof after I am done, the sad thing is that none of those have gone out on my truck yet. 75K miles and still no major issues except for the EGR failure at 22K miles. Still under Ford extended warranty, so i cant mess with it too much right now, in case something serious does happen and I run into a hiccup. but that expires in November.
