For your 10703 model (short wheel base regular cab, C10) with the MM7 transmission (4 speed manual with overdrive) and LE3 (250-2bbl inline six) the GQ1 ratio corresponds to a 3.08:1 rear axle ratio.

The standard axle ratio with a 305 (350 wasn't available in a 2wd 1/2 ton) and a 700R4 was 2.73 to one, and 3.08 was an available option, so yes, those gears will work fine.
