You could order specific options on a 1971-1972 LeMans to make it nearly identical to a GTO. In fact, in 1972, the GTO itself became an option on the LeMans.
It looks like whoever ordered your LeMans wanted a GTO, but without the GTO nameplate that would have kicked up their insurance rates. They ordered the Endura Styling Option, 400 4-bbl, G70x14 tires, Springs & Shocks, all part of the GTO package.
