Gt ypur pm message. sorry but was off the site all yesterday with daughters dental surgery issues. now to help as best I can. I'm guessing this boot needed is the rubber piece for the connection to the filter to the turbo housing. About all I can suggest is typ4 aka russ who is in Oregon or agnem aka Mel of Conestoga Diesel in Pa. Of these 2 members I feel Russ has what you want. He recently purchased all the parts from ATS so he is the best bet for this boot. Mel mite be closer and may have what you want also. In a pinch you mite be able to wrap some duct take around the boot to make it seal for the short term. In my over 18,000 posts this has never come up here as a wear item or needed item. I will call you and try to help.
