    Be careful, I had a 94 ECSB Z71 that had 3.42&#39;s. They did come with different ratios. If there is no tag, you&#39;ll have to pull the cover and count the teeth.

    Start by looking at the codes in the glovebox.

    GT4 3.73 (most likely)
    GT5 4.10
    GT7 3.33
    GT8 4.10
    GU2 2.73
    GU4 3.08
    GU5 3.23
    GU6 3.42
    GV2 5.83
    HC4 4.56
    HC7 5.13
    HE3 3.07
    HF7 4.56
    HF8 4.88

    Hope this helps

    You never know

    Found the codes, never found out where some of them came from but always nice to know more than I need.
