ps reverse is never counted in the 'speeds factor' unless maybe it's a 'Champ',,.

Thanks Dennis,

I repeat my question - does this truck have a four speed gearbox & one reverse gear or is it a 3 speed box with one reverse gear.

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

Tony I am fairly certain the blitz has the same box as this Chev and as the 4 speed bit has been answered twice above in obscure ways I won't obscure the answer anymore

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.

Tony, are you saying there are "IMPROPER" parts books out there?

Thanks Tony succinct as always. Much appreciated as it is very helpful.
To Cliff & Rusty thanks fellahs also.

Had a Gecko climb out from under the valve train when I took the rocker cover off. So Im off to a wreckers to look for a replacement engine.

Hi Tony,
The gearboxes are the same, except for maybe some brackets bolted to it for stuff like transfer box shift mechanisms etc. Thats my opinion from looking and working on my two trucks anyway.
Should mention the actual gear stick is diferent. The Blitz bends forward, while the truck bends back or nearly straight

Thanks Robert & Max...fantastic info.

And to Rusty for the info about the Hardwoods.

Still out at my brother in-laws fixing an old inter AA160. Got her spinning like a top today. Got no brakes.... but one step at a time.

Interestingly enough it has a Military tow hook on the back. Looks like a dodgey add on but Max tells me the army did have some of these trucks.

Anyway it had not run in ten years but she's been revived for a bit of farm work. Going to put a roof on a shed to keep her out of the weather as well.
