My 70 4 speed car has one also. But I have seen many other 70Z's without one.
What I never could understand is the chart I attached a link to. It shows cars with a wide ratio (M20) getting one but cars with a close ratio not getting one. What difference does the trans ratios make??? The internal speedo gears are driven by the output shaft so the gears in front of them make no difference. Not to mention that in 4th, all Muncies were 1:1 anyway. Am I missing something here?
