wanted: Chev CMP chassis views

Now that we have the rail taper question solved, I would like to have some input on my 2nd question please:

Is the only difference between the C60S and C30 in the axles used? 3-ton axles versus 15-cwt axles and heavy versus light steering box?

I am trying to ID a Chevrolet: it is said to be a C60S, but it is on 10.50-16 tyres, which could mean it is a C30. But it does have helper springs on the rear axle and the front axle knuckle has 6 bolts on top. Can anyone help?

Thanks,
Hanno

Hanno I have always thought that the 30cwt trucks had no helper (overload) springs whereas the 3 ton did.

Not very good quality pics, but they show the 6-bolt steering knuckle ("heavy" or 3-ton axle) and rear axle helper spring. Tell-tale signs of a 3-ton C60S, rather than a 30-cwt C30, right?

Do 16" rims fit on 3-ton axles/drumbrakes?

Chevrolets are not my strong point, sorry

Thanks,
Hanno
