As best I have been able to determine, the following information
is the general specifications for the MKIII model Triumph GT6.
This table primarily covers the US market accept where noted.
I have made all reasonable attempts to verify all information
contained here. It is by no means, that I claim these are
the true and only versions of these numbers you'll find.
