For my panel, I found some bucket seats out of a late '80s 2-door Isuzu Trooper II. They have a fairly low back, so they still look somewhat like an old truck bucket, but they have headrests. The passenger seat folds forward for access to the back, and I found some inner armrests from a different Trooper that I'm going to mount on my seats. They should look quite nice in my slightly modernized panel.
