I think you can get away with just changing the hinge pivot bits
themselves. The front-most crossmember is basically the same for all
Spitfires and GT6s, differing only in location of various holes, blind
nuts, etc. for valences and spoilers and other pieces that bolted to it.
Otherwise the panels will line up: older bonnet on newer body and vice
versa. It might offend some folks' sense of aesthetics, originality, etc.,
but it will work.

Correct. Reverse is to the right of 3/4 on the single-rail, and to the
LEFT of 1/2 on a three-rail. Of course, there are two different three-rail
gearboxes: one with and one without the synchro first. Assuming
originality, the later all-synchro version is easily identified visually
by the larger output flange (round, taking the larger flange bolts).
And either three-rail is very easy to tell from a single-rail if you can
look at the gearbox itself (tunnel cover off or gearbox out of car), as
the top cover and shift extension of the three-rail gearbox look very
different from the remote shift arrangement of the single-rail box.
