Speedometer gear for ACN transmission?

[supersisu]

I just swapped out a 4 speed trans (I don't know the code, have to check) for a 5 speed ACN. According to a chart I have, the 5 speed is from a 1.8 gas set-up. My 1980 diesel truck has a white speedometer gear (which popped off during the swap) and I'm trying to figure out what color I should get (red, green, another white) to get reasonably accurate speed. Although I use the speedometer more to track mileage as my fuel gas reads high which has gotten me into trouble. Appreciate any help.

Broke's page says you need the red speedo gear (unless you have tiny tires)

62 : 17 = 3.647 (15T) red

66 : 18 = 3.667 (15T) red

74 : 19 = 3.894 (16T) white

63 : 16 = 3.938 (16T) white

67 : 17 = 3.941 (16T) white

68 : 16 = 4.250 (17T) green

I need a white gear (lost mine doing a swap, doh), so holla if you want a couple of bux for yours, or want something to swap for it.
