Here's some park light pix.

Hi everyone! (my first post)
I am scratchbuilding this truck in 1/43 scale, and have some questions about frame dimensions.
According to the dealer’s handbook, for the US-produced commercial truck, the frame maximum width is 36”, getting narrower at the cab section, down to 25 7/16” at the forward point. I scaled down these dimensions, and finally got a construction, looking not the same as well-known 1/35 kit by Tamiya. Upscaling the tamiya kit frame, we have these dimensions like 37,7” and 34,5”…
The visual difference can be seen at my picture.
Due to the lack of information, I have to use the Tamiya kit as 3D drawings, and, already discovered some mistakes, like the spare wheel is not placed in its originally position, in the aft left platform corner, due to omitted cutout in the aft left wheel housing. Due to this mistake, none of built kits I’ve seen, have the rightly positioned spare wheel. But, in general, this is a great kit.

My question is, whether the frame had any visible modifications (e.g., extended width) to meet some military requirements, for Canadian built machines?

Another question is about fenders size and shape. They are a bit shorter, and also look wider, than for the commercial model, for the wider tires use, I suppose. Could anyone confirm my idea? And, how much in mm, or inches, was this difference?

Also, the engine hood is looking a bit wider at the firewall station, or am I wrong?

Appreciate for any picture of the chassis, and maybe a factory drawings… I would buy, if they could be sold.

By the way, many thanks for valuable photos and information in this thread!!!

Now I assume your questions relate mainly to the differences between the Tamiya kit and the real vehicle. Your #1 mistake is to use the Tamiya kit as the thing to scale down from as it is not correct to scale having some major incorrections in the chassis and in the front sheetmetal. The cowl/firewall/bonnet is too wide as well.

My question is, whether the frame had any visible modifications (e.g., extended width) to meet some military requirements, for Canadian built machines?

The chassis had the same dimensions as the standard commercial chassis.

Hope this helps

One LRDG replica was produced by sacrificing a rebuilt 1939 Chevy...plus a Canadian military '42 pattern thatg was ex-Showman's. However, and thius is wherte I start crying, it was the last surviving '39 normal-control Chevrolet built in the Southampton Plant. There is now just a '39 COE and a sedan, if it is still extant in Italy to where it was sold, surviving from local production.

Sorry..got to go to cry me eyes out!

Oh...didn't the '41 and '42-46 trucks have different sidelight locations? The '39 and '40 trucks had different lights as well as the different grille that looks at first sight to be the same.

Thanks, Cliff, any information is appreciate.
Was the fenders width extended, to compare with the civil model?

The fenders were cut out to give the larger sand tyres more room.

If you got to here http://s108.photobucket.com/albums/n17/MrRoo_2006/ you will see some of my models including some adaptions of the Tamiya Chev kit in 'sub albums on the Right Hand Side along with a few oddball CMP models. You will see how the guards are cut out there.

On the civvy trucks the one tons and smaller had the fenders with the small wheel openings. The ton and a half trucks had either the small or large openings. The two tons and larger had the large openings. The military trucks likely all used the large openings to clear the military tires. The military wheels were offset more than the civvy ones so gave a wider track.
The 40 and 41 trucks had the narrower grille with the headlights mounted beside the radiator. The 42 and newer trucks had the headlights mounted on top of the fenders.
All the trucks from half ton on up used the same frame dimensions from under the cab to the front bumper. So did the C8 and C15 two wheel drives. The heavier trucks used thicker material in the frame and some had doubling plates on the outside of the frame rails.

WOW, Thanks a lot for many pics to study!
I scratchbuilt chevy and Timken rear axles, too, for 1/43 projects.

Here, part of my 1/43 military diecast collection, including the chevy building:
http://rcforum.ru/album.php?u=25356

I studied the available pictures of the LRDG trucks, but they not seem to have too big wheel openings, as seen on some other similar chevy trucks. The LRDG fenders look modified: shorter and wider, like seen at the first picture attached - the side steps shape indicates the oversized fenders, to compare to civil models, although this is not exactly LRDG, but at the second picture, the similar truck is described as 1533x2… is this correct description? Very interested, the total width of these fenders.

Hi Igor:

The Chevrolet wreck lying in the desert of Egypt was most probably used by the SDF (Sudan Defence Force) but it is not an LRDG truck.

The other Chevrolet shown on your B/W photos was originally used by the Free French. The caption is totally wrong.
