Will a 2008 F250 short bed shell fit a 2018 F250 short bed. Found a 2008 fiberglass color matching one.

 

I started a thread a couple days ago with no answers wondering about the leer cap on my 2012 fitting a 2021. I guess I'll have to measure my 2016 bed rails then go to a dealership and measure a 2020/ 2021. Cheaper to take my leer cap and get it repainted then buy a new cap.

 

No they won't. Completely different bed and rail height. Tailgate/Door also significantly different

 

No, it will not mount properly and your going to want the rear window cover that goes over the tailgate. I too wanted to swap my old one over, but new truck means new topper. I have a Century and absolutely love it.
