I've always wondered about the bow in the grill. In any case the one in mine
is flat. With regard to the air passages ... In # 78 (spring 2001) of the VTR
magazine, "Maintenance" section, TeriAnn Wakeman provided some explanation
... summarized as follows; aftermarket grills had opening holes 7.2cm (2.84")
X 1.3cm (0.5"), while the original grills were 7.7cm (3.03" x 1.6cm (0.63")
... a difference of 24% more area for air to flow to radiator. I have checked
this out when I've seen grills come up on ebay, and sho enuf, when I did get
replies these measurements held up. I see now the TRF has a grill replacement
that they are claiming is "Better" than the previous replacements, I have not
however asked them for the measurements.
