    Can someone tell me where I can buy speedo correction gears for an NP 241C transfer case. I have changed the gear ratio in the axles and would like for the speedo to read correctly.I have tried Bowtie OD, but they only sell gears that go in the transmision, not the trans case.

    Go to a GM dealer, you will have to know what combination you need, but they can get the gears for you.

    I called the dealer and was told that they can only supply gears for 235-75-15 or 31" tires. I need gears for 33" tires and 3:42 ratio rear end.

    you can either get 35 and 17's or 37 and 18's. you might need a new carrier for the new driven gear. your dealer should know the split for carriers.
