I use to have one of those! Back in late 1984 (19 yrs old), I bought my first new car - a 1986 Nissan 720 pickup truck. Completely stripped - no radio, no AC, bench seat. The only "extra" I bought was light sky blue paint. And of course, I modded it too! Lowered, stereo, Mustang bucket seats, t-top, bed shell with a rag top, etc. Even my engine was painted light blue with pink pin stripes.
Sounds like we had the same truck. I had a bare bones stripped base white 1986 Nissan pick up too. Drove the wheels off that thing. Too poor back then to afford mods, but I added a cheap kraco radio and speakers to have something to listen to. Lots of great memories from those years with that truck.
