They appear to be inter-changeable. I didn't look into the fender wells but I can't imagine they'd be different.

Why spend the money ? Many people who buy older trucks almost always start looking for fender flares . Besides even if you find some the same color they still might not match and then you will have to have them painted.

 

Well one of my fenders is extremely rusted out and I don’t like the look of the factory flares. I was planning on painting them.

 

Your first post read like you just wanted to replace the flared fenders becuase you did not like them.

 

What about the rear fender flares?
What color is the truck ?

 

I’m building a flatbed for it because the box it totally rusted out.

 

It might be a good idea to have a body shop inspect this vehicle for rust elsewhere that might make it unsafe to drive . You always can't see all the rust . Rust never just stops , it just gets worse.
