Access Cab Rear Seat Question

Hi all my old man recently purchased a third gen access cab but it's the one without rear seats. He's wondering if he could add seats later on down the road. Any one know if this is possible?

 

Yes.

 

Doesn’t leave much room in the back. I’m doing a rear seat delete in my DC. Still building a platform.

 

I’d gladly trade with him. He could have my seat assemblies and trim if I could have his seat delete kit.

but: I’m in between jobs AND moving right now, so . . . . not doing any truck projects for a good while
