Well ... I know of a guy, who had an '84, that put an early style bra on
the front that covered the lower grille and it caused an overheating
problem.  A problem he never had without the bra.

Some have "Thought" that, because some air cooled vans that had air
conditioning and had the lower grille for that reason, the lower grille
was only needed for air conditioning.  A bad assumption, I'd say.
