There's a 2006 Harley ext cab being parted out near me. I have the 2000 f150 ext cab looking for a new fresher interior.I know something can always be fabricated for the front, mainly concerned for the bench seat in the back. Wondering if anyone has done anything like this before... or if some one can kindly steer me to the right directions of a similar build/ mod.

 

Sorry, I can't answer your questions directly....but if you want a different look ...I'm sure it can be done. Just how much effort and money will be thrown at it, is the unknown.

Just do some judicial measuring for the front and the back. I was thinking that the 06' were wider then the previous generation (gen 10 vs gen 11).
So with a full length rear bench seat, it might be a real struggle getting that 06' rear shoe horned into your 2k. If the width is pretty close then you have chance at it.
