A little Trooper history. The Trooper came out in 1981. The original, first generation, had round headlights. People call them "round eyes." That's the Style I am building. I think they look the coolest because of the old school round headlights. They made round eyes from 81 to 86. One other quirky thing about the design is that the wind shield is entirely flat, no curves or corners. Another interesting fact is the Trooper was badged as an Isuzu in the US, but was a Chevrolet in Indonesia and some parts of South America.
In 1987 the front end was changed to square headlights. Still a good looking grill, but the round eyes are still the most popular. The change was cosmetic only. It's popular to put a round eye grill and headlights on a later square headlight truck. I'm looking for another round eye grill and corner lights if anyone has them. Many people on the Trooper forums talk about 3D printing round eye grills, but I've never heard of anyone actually doing it.
In 1989 they went to a redesigned body style (2nd Gen) that was rounder and much less appealing if you ask me. I like the simple boxy body lines that made the gen 1 look utilitarian instead of the minivan like 2nd generation. Like many early Japanese designs they are small on the outside, but big on the inside. The seating position is upright and the door cards are flat panels.
