NOTE:
In the last year of G-body production at Buick, the engine package was
available as a Regular Production Order (RPO LC2) on any Regal. In other
words, the Turbo engine was available on any Regal with a huge variety of
other options. The LC2 engine itself required another "option",
a suspension upgrade (to the FE3 package), and the suspension itself
required, in turn, a specific set of factory wheels with wider tires. Only
two possibilities here: the chromed steel GN wheels weighing 27 lbs on the
Grand National, and the aluminum alloy "T" wheels weighing about
17 lbs on any other Regal with the LC2 option package. The style advantage
went to the GN wheels while the functional advantage was clearly with the
"T" wheels.
