Is it a Chevy or a Ford ?

Although Chevrolet and Ford of Canada CMP vehicles both look similar, there are in fact a number of differences between them, some not as obvious as others ;

Badges

Fords had an rectangular 'Ford' badge (oval in later models) and Chevrolet a bow-tie shaped 'Chevrolet' badge , both on the radiator grill.

Bumpers

Ford F8, F8A and Chevrolet C8, C8A and C8AX had 5" wide front bumpers, all others were 6" wide.
C8 and C15 had a cut-out for the starting handle, all others had an extended bracket on top of the bumper.

Scripting

Some Ford models were scripted under the headlamps.1942 models with Ford Canada under both headlights,
1944 with Ford under LH light, 1945 with Ford Canada under LH light, there seems to be no set pattern.

Vents on No11 & 12 cabs.

Fords had four louvres punched into the steel and Chevrolet had a round hole covered in a mesh grill.
2 vents were fitted, 1 each side of the radiator.

Chassis

Front spring rear hangers, on a Ford it is a cast iron horn shaped bracket rivetted to the chassis underside, on a Chevrolet it is a cast bracket rivetted to the chassis side.
Gearbox mounts, Ford has a cross-member mounted to the rear of the gear box with a hole in it for the ouput shaft, whereas the Chevrolet has a cross-member which passes under the gearbox.

Differentials

Chevrolets had 'banjo' differentials, Ford had Timken type split type differentials.
Some early F15A trucks, FATs and later F60Ls used Chevrolet axles.
Some F15As had banjo rear axles and split front axles.

Doors

Both had a reinforcing cross pressed into the inside of the door panel, Ford's met in a small circle.

Engines

Chevrolet had a 6 cylinder in-line overhead valve, Fords had a V8 side valve.

Gearboxes

Chevrolets had a P.T.O. on the left side, Ford was on the right.
Reverse gear was on the left on Chevrolets and on the right on Fords.
Tyre pumps when fitted to the gearboxes were left-mounted on Chevrolets and right-mounted on Fords.

Radiator grilles

Chevrolet grilles were made from expanded sheet in a diamond pattern, Ford grilles were from woven wire running vertically and horizontally.
Some exceptions were early cab No 11 Chevrolets which had the woven wire type.

Brush guard

Ford guards were leaf spring like and mounted either behind the bumper or in front, Chevrolet guards had two separate uprights one behind and in front of the bumper and was wider than the Ford.

Grille bar

Chevrolet had a horizontal bar behind the middle of the grille, Ford had no bar.

Horns

On the Ford this was mounted to the rear of the bumper on the left hand side, on the Chevrolet it was mounted on the engine inlet manifold.

Instruments

Ford and Chevrolet used their own style panels until late 43 when they started using round style US gauges but with their own switches.

Mirror brackets

Chevrolet mirror brackets were mounted onto the upper door hinges, Ford mirror brackets were mounted between the upper and lower door hinges.

Overflow tank

On Fords this was under the passenger floor on top of the left front chassis rail. Chevrolets were also here after mid 43, being previously mounted above the left front mudguard behind the sidelight.

Pedals

Ford clutch and brake pedals were round, Chevrolet were rectangular.

Cab roof hatches

Chevrolets had a single grab rail in front of the hatch, Fords had two small handles.
Hatches were rectangular up until 1944, when they changed to round for both manufacturers.

Steering boxes

Chevrolet boxes were mounted on a cast bracket next to the right front chassis rail, Ford boxes were mounted on top of the right front chassis rail.

Steering wheels

Chevrolets had a four-spoked wheel made of hard black plastic prior to July 1943, after that it had a wood rim.
All Fords had a black hard plastic wheel with slightly curved spokes.

Electrical system

Chevrolet and Ford both had 6V systems on most* of their vehicles, the main difference being Chevrolet was negative earth or ground and Ford was positive earth. Great care had to be taken when interlinking vehicles during jump-starting.

Note ;

As with all production manufacturing, changes were made due to revised designs or materials shortages so the above list should not be taken as a 100% accurate summary of the differences between the two major CMP manufacturers.
We would be interested to hear about any other differences or examples you may know about.
