That 6th picture looks like a bad photo to me, like it was bad lighting that it appears to have a liner. I just washed the inner fender wells with westly's bleech white, then scuffed the rear fender wells with a 3-m scotch pad and then bought 2 cans of spray on bed liner from Autozone. I used a can in each side and it looks real good. I am thinking about doing the whole underside of my truck with that spray on liner. It is made by dupli color.

 

Post a picture and how much was it for a can?

 

The pictures are not perfect, but they do show the liner. Look at the raised area over the rear bed-side brace. They DO have liners. I saw one at dealer today, looks like they could be addapted easily. I am headed to Parts Dept Monday.

 

I have those liners on my 04 fx4

I think it is a flareside thing. Or maybe a Canadaian thing

 

I will try to get a pic of it today, and i have to find the receipt for the price..
