You can rotate it, and count the revolutions. Less than one turn, or more that one complete turn. Jimmy Bill wrote:
OK...now how do I tell which ratio adapter I have? A 1.250 or an 0.800? The parts book says that the .8 should only be on a 904 and a .8 should only be on a 727, but I want to make sure for myself that I do have a .8 unit. Is it marked on it somewhere? And who is the best source for these things these days again? Thanks Bill M 65 Coronet 500 'vert On 5/18/07, Gary H. <62to65mopar@xxxxxxxxxxx> wrote:For your 1965 (or 1962s to 1965's) A. Divide 63.36 by the car's tire circumference. The circumference is tire diameter times 3.14. (e.g.,a 26 inch tall tire has 81.64 circumference so 63.36/81.64 = .776 B. Multiply that result by 8 (8 x .776 = 6.208) C. Multiply that result by your axle ratio (e.g., 3.23 x 6.208 = 20.05) The result is the number of teeth needed on your car's speedometer pinion, or 20 in the example above. Gary H.
