I'm finally getting around to fixing my speedo. I went from 2.77 rear gears to 3.42. I had a red drive gear w/ a blue driven gear for the 2.77's (stock). I went to the dealer and got a grey drive gear and a yellow driven gear which according to this site says is good for a 3.45 rear, close enough.

I have 2 questions:

1) I have a small "sleeve" from my stock speedo gears and a larger "sleeve" from Pro-Built when he sent the tranny. Which sleeve do I use without destroying the speedo gears?

Am I correct in assuming since my stock blue driven gear had a smaller sleeve that it is sleeve #25007338 as shown above? And does my new yellow driven gear require sleeve #25007339? If so, is sleeve #25007339 the larger one I got from Pro-Built?

2) The "rod" that the driven gear spins on is from my stock blue driven gear and I slid it on the new yellow driven gear. Is this ok? Does the new gear require a different rod b/c it seems to slide in and out of the new driven gear pretty easy.

One more question:

The new yellow driven gear is larger than the stock blue one. Does the sleeve compansate for this or what?

I know someone knows, we've had A LOT of people here do gear swaps. Is the #39 sleeve larger than the #38? Can I use the rod of the blue driven gear on the yellow one? Why is the yellow driven gear RIGHT next to the larger sleeve whereas the stock gear was not?

I looked at the numbers printed on the larger sleeve and my driven gear was listed on it. I tried everything out and it works. The rod also seems to be working fine.
