My 93 k3500 454 dually had 4.10's. There's a decal in the glovebox with a bunch of 3-letter codes on it. One of them will tell you. I'd be happy to check Alldata at work to decipher the code for you......

hope this helps.
IN YOUR GLOVE BOX THERE ARE CODES GM USE'S.
TO FIND OUT WHAT GEAR RATIO YOU HAVE HERE THEY ARE: GU4 IS 3.08 .... GU6 IS 3.42 .... GT4 IS 3.73 AND GT5 IS 4.10 THESE ARE THE GEARS THAT COME IN 81-04 FACTORY AND IF THERE IS A G80 BY THOSE CODES ITS POSI.
