I have a 04 F250 Ext-cab and need to replace te passenger side step rail OEM style what years were they the same steps and what year will bolt dirctly up anything newer? Will the newer tow mirror fit the 04? Thanks

 

Yes newer tow mirror fits. Just have to splice harness. The plug isn't the same. I did mine in virtually no time at all. Search the forum, plenty of info on it

I would say 99-07 steps should all be the same. Perhaps 08-16 but I'm not sure
