I am mostly complete with the interior makeover of my 81. First some pics of the starting point when I bought the truck.
I found a set of door panels in really good shape locally. I also found a later (92 or so I think?) bench seat with the headrest humps, which I liked better than the flat-top bench that came in the truck. I got it reupholstered at a local shop, nothing fancy, just a good imitation of what might have come stock. I also had them recover the really sad dash pad, which they did for a really good price.
SEM Color Coat Pacific Blue dye/paint on the kick panels, a-pillars, dash and door cards.
Then some carpet, door weatherstripping and window fuzzies from LMC.
I had already redone the instrument cluster, so that was all set to go.
And finally, a classic look radio with modern guts and bluetooth, Polk audio speakers in the doors, a Blaupunkt amp and some 6x9's behind the seat.
Here's where it's at now.
Now to figure out the mysteries of the HVAC system.
