looks great!! thinking about doing the same swap in mine. new carpet, bucket seats and center consol. that carpet is in awesome shape for finding in a yard!!

 

From the pics it looks as though your driver seatbelt is frayed. I would replace that as soon as possible. That would concern me more than the rest of the interior.
Truck does look awesome now, good job.
Doesn't Toyota (and other manufacturers) have lifetime warranties on seatbelts?

 

Would be nice to know. Mine are starting to get a little rough too. You can only slam them in the door so many times
