Gotta love that quality 80s GM fit and finish!
And that Regal is very oddly equipped. Bench seat, manual locks and windows, no rear reading lights.....but it has alloy wheels.

That cluster must be from a pre-production vehicle, as the tach was never red like that on any of the production ones. My old 88 Regal was a November 87 build, and the tach was green like the rest of the cluster.
