Part # for speedo gears (T5)

Does anyone know the part number for an 18 tooth driven gear that fits on a 1992 T5. My local GM dealer can't find it.
Thanks

Thanks, but I've seen that post before and the only part # listed are for the 700R4 tranny. The T5 use different parts.

Someone on that site should know ???????

So far, I have seen these choices for the T5:

Drive gears:

6T
7T
8T
9T

Driven gears:

18T
19T
20T
21T
22T

FYI, this equation is if you know what driven gear you have:
Drive Gear = (.0495835 * Tire Diameter * Driven Gear) / Gear Ratio
