I looked through some of my 95R pictures and found this one, maybe it will help?
Definitely 1994 dated.
If I remember correctly, the 1995 Cobra R Dearborn build documents that I have say that these 5.8's were built in late 1994.
I will have to look at the 1995 Cobra R Unique Parts List or the 95R assy. line build add/delete list that is in those Dearborn build documents to see what wire set was used. I know the 1993-95 Lightning also had a red 5.8 wire set, but for some reason I thought I read a F5Z part number for the 95R, not a F3 Lightning number? I don't remember for sure, it has been almost 10 years since I was Cobra R literate.
I was wrong about the Lightning, according to the Dearborn documents, it was a 1993-1995 SVT Lightning set of wires that was used on the 95R 5.8...........
^^Those documents come in soooo handy when trying to figure out what Ford/SVT did when they were engineering the build for this unique car.
When I was looking for the info. showing these spark plug wires, I also found the memo where the Convert. X-Brace was deleted from the 95R build because of assy. line installation issues.
