    Ive got a 1984 Blazer with the original rear and and axle ratio. My RPO code is G80 for Gov-lock and then GQ1 which is listed as "Standard Ratio" What is the ratio that GM is refering to as Standard ratio? I couldnt find anything listed on the axle tubes. I know I can jack it up, or take the cover off, but im just wondering what ratio GM uses as "standard ratio"
    Thanks

    http://www.slosh.com/cars/brochures/ the brochure for your year will tell you standard ratio, which was probably based on engine/tranny combo, and if it was a CA truck or not. I'd guess 3.08 or 2.73 though.
