Does this vehicle have the same gearbox as the Chev Blitz?

Drawing on my vast Chev knowledge (
), the gearboxes available at the time were similar to the options offered by Ford. That is, there was a 3 spd synchro box in Cars and a 4 spd crash box in trucks. The crossover point was in around the 3/4 to 1 ton ute range. The GM 4 speeds will be broadly the same, with small variations like clutch/bellhousings, input lengths, spline counts, output shaft types and ancillaries such as handbrake locations.
There may be a chance that the box is
identical to a Blitz, but more likely to be
similar with interchangeable parts. The only way to tell is to have the two boxes on a bench side by side, or to have the PROPER parts books and compare part numbers.
