TR2 grille question

["Mark Gendron" <mister_toad@email.msn.com>]

I just received a die-cast TR2 grille that I purchased on eBay. I noticed
something odd: it has two lugs located in the center of the grille on the
engine side. The lugs are spaced 4" apart horizontally. Each lug accepts a
small machine screw. The die-cast grille from my long-door does not include
these lugs. Does anyone here know what they're for?

Thanks
