I have 2004 F150 SC with the 11 digit of the vin being a "F". The problem is that
when trying to order rotors under the 6 lug pattern it says the 11th digit should be a "N" or "K". My questions would these be the correct ones to buy even though my vin letters don't match? Has anyone ever run into this?

 

This is why I get frustrated buying this kinda stuff online. I can't be bothered, my issue usually is what is the stud diameter, 12mm or 14mm and do I want the better rotor or cheaper. Said and done, a few minutes. I only order online for aftermarket kinda stuff, accessories mostly. Sorry not to add anything, just it's stupid how a "required" item blocks ordering progress and has nothing to do with anything. It should be 1 for 4x4, 1 for 2wd, I'm thinking for any given year, that is the only difference, no?

 

I originally ran into this problem when I went to Carquest and was asked this same question. I was told to bring it in and they would match it. I just thought it was pain when they are a ways out of my way to begin with.

 

I know what you mean but the parts guy there must be kinda dumb. In my experience, how do you find out the stud size? Go in their book and find what wheel nut goes to which stud, 19mm for 12mm stud (mine) or 14mm stud to a 21mm socket. That was the case for that because I think in 01 or 02 they increased stud size, 04 and newer should have the same sizes as well as all be 6 stud. It's alot of confusion for really nothing.
