    can you tell me what gears would be in this k20? the vin is cky244s103781 if that helps. i believe its a 74 if my vin knowledge serves me correct. theres no glove box sticker, and i dont really feel like pulling the cover since theres no wheels on the truck./forums/images/graemlins/eek.gif aid in my laziness, please. /forums/images/graemlins/thumb.gif

    What's it got for a drivetrain?
    Manual or Auto?
    Engine size?
    Only then can one make an accurate guess.
    But, my thinking at this point is 4.10's

    14ff and 44. judging from the vin, it was a 350 stock. original tranny was a 350 as well. /forums/images/graemlins/thumb.gif

    I think 4.10's were the most common ratio in the 3/4 tons...
