[TR] TR3 Threads

> Your TR3 should not have any Metric threads

Sorry, but I disagree.  The studs that mount the instruments are metric
threads.  If the transmission cover is threaded for OD & reverse light
switches (as most TR3 covers were), those are metric threads as well.

There are also several places where there are British Association threads,
which are fundamentally metric threads (based on the meter) even though most
sources give them in oddball Imperial equivalent measurements.  For example,
the screws that hold the chrome "toilet seat covers" to the spare tire lid
are 4BA, which are 3.6mm diameter by 0.7mm pitch.
