This part will NOT fit a 1999 Ford F350 4x4 with a 6.8L petrol engine manufactured in early 1999 or late 1998. However, the driver's side does not come close to the shape anyway. I was told it would fit my 1999 F350 exactly and NO NO NOTHING. I'm just glad my driver's side was cleaned and repainted to make it look new again. Track what you order and just know that the right app isn't the right one, but maybe 50% of the time. For the money I spent I screwed up a lot. $90 for a semi-working product. SMX.
