I might be way behind, but has anyone put 2005 fx4 running boards on a 1999 lariat? They are obviously the right length they are off of an ext cab and they are going on an ext cab. I used to have the boring old gray running boards these are the really nice chrome flat step bars. Anyway, will they work?? Should they bolt right up??

 

I guess the only way to know is for you to try.
