FYI, on my replacement I found the section that goes back to the firewall to be about 2-3 inches too long. Kind of pushed the whole thing forward. It turns out that there is a short section back there that the updated replacement assembly is evidently intended to also replace. Atleast, on my 2008 thats what I found. My Amazon history shows Motorcraft part KH-509, where its $60.98 today Prime, little less from other sellers with free, who-knows-when-shipping. I purchased for $46.18 in Jan of 2018.
