Searched FTE for compatibility of 2000 F350 upgrade to 2007, couldn't find anything.
Ebay has kits for sale, for around $500.
Question, what mods need to be done to my 2000?
Question 2, is the products on Ebay cheapee, or should I look for OEM when I do the upgrade?

 

Haven't done this Update myself but iam sure there are others on here that have...
Although i did sell all the "stock" parts off my 2006 to a guy w/a 2000 so he could do that update & from what i understand you will need:

1. Headlights
2. Grille
3. Bumper (because newer Grille is larger so bumper is cut in)
4. Wiring Harness adapter for headlights

Apparently it was all bolt-on except he had to cut out a small part of the Support for the newer headlights to fit all the way in.......Iam told its easy

*As far as your 2nd question, i bought my Harley Lights off eBay (Eagle-Eyes if i remember correct) & they work great
I even tore them apart to custom Paint then re-sealed & ive never had an issue w/moisture...
