The 1967 Plymouth Belvedere is somewhat confusing. The Belvedere was available in four different trim levels: Belvedere, Belvedere I, Belvedere II, and GTX. The entry-level Belvedere was available only as a wagon. The Belvedere I was available as a sedan or wagon. This car is a hardtop coupe which was only available in Belvedere II and GTX trim. However, the emblem on a Belvedere II would read "Belvedere II," which this car does not have. A GTX has two fender emblems: "Belvedere" on top and "GTX" underneath. So I'm wondering if this is a GTX that has had the "GTX" emblem replaced with a "440 Magnum" emblem, (which happens to be the standard engine in the GTX). I don't know for sure.
