NBS is my second favorite. They are much nicer trucks as far as comfort and hope to build a crew cab one day.
That engine bay is clean. I also like the instrument cluster.
I cant remember, did they switch from the circular gauges in 1990 or 1991? My dad had an '89 step side when I was a little kid. I thought that style speedo was coolest thing ever. I was born in '87 and he sold that truck in '91 when his new '92 came in (I was VERY young). I cried when he sold that truck. My dad still tells that story to this day.
I believe 91, because the 90 cluster looks like 88-89 on the 454. Mine was swapped to a Dakota digital setup so it’s more modern now.
