RE: [T3] Tune Up & Brakes

["Fuhriman, Mark" <MFuhriman@fugro.com>]

Regarding that 43 mm measurement to fing¹!. BTDC... Sounds like that
measurement would apply for a Type 1 pulley, *not* for the Type 3.  A 43 mm
arc length and 30-deg. angle corresponds to a pulley diameter of 164 mm
(about 6.5 in.).  That's way too small for the Type 3.  

What IS the diameter of our pulleys?  I think I read somewhere that the
diameters vary depending on early or late (1972+ ..?).  Does anybody know?
