3-ton GS body mounted flush with rear of chassis frame?

I seem to remember there was a description about this one of Bill Gregg's publications(?)........ and it had to do with the style of tyres; If a truck was fitted with Run Flat tyres, no spare was needed and the body could be mounted behind the cab directly. If it had normal tyres, the body could be mounted backwards leaving room for a spare tyre carrier behind the cab.

I looked up Volume 5 - Bodies and Non-technical Vehicles of the AEDB Design Record, and found references to 3-ton GS body with 54" wheelhouse which came both in all steel and composite construction. It is clear it was designed so it could be fitted in two positions: either with a 14" overhang or flush with the chassis, although I could not find a reference why/ when the body should be mounted in each position.

See the attached pics of examples of Chevrolet C60Ls with Cab 11 - with runflat tyres hence no need for a spare like you noted Alex?

That's what remember reading somewhere.....and to me it makes sence. I also saw Phil mentioning the same things in another thread.....he also couldn't remember where he read it!

As always, new info and new pictures also raise new questions.....I always thought the wood/metal composite body was a mid to "late" war development, so I am surprised to see it on a Cab 11 here (?)

Sometimes the answer is right in front of you.


“The body is mounted with 14” overhang on the 158” W.B. short frame, and flush with the rear of the chassis on the long frame”

Jordan, thanks, I’ve read that. This suggests the 158” wb chassis came in a long and short version. As far as I know there was only one type of chassis frame. I did read about frame extensions, I think Keith Webb photographed some on a survivor in Australia.

the extended frames move the trailer hitch back the 14 inches to the rear giving a better tow geometry.

Thanks Harry. Are those extensions bolted onto the standard chassis?

Hi All

Years ago when I wanted to put an S56 radio box on the back of my C60S Pattern 13, I made up a extension that used all of the existing bolt holes for tow hook assembly. Consist of inner frame rail, outer rail that buts to the normal frame and rear cross member. All the steel matches the regular frame.

The it has turned out to be very rigid. I'll take pictures and post.

Cheers Phil

the one I saw and the pictures I've seen suggest factory.

Hello Hanno,

Thank you for attaching the diagrams and the photographs. So the difference is a 14 inch overhang over the rear of the chassis - as the most common configuration. The less common alternative is the rear of the body being flush with the end of the chassis. The diagrams made it clearer. With most of the photographs being at a 3/4 angle it was hard to tell the difference. Well to someone who is not very well schooled in things CMP. I am more in the MCP camp.

Kind regards
Lionel
