4x2 or 4x4 and some other questions

[Glenn]

Hello again.

Were there any Ford 4x2 158" 60 cwt-3 ton CMP vehicles? If so, which model/year? Or were they all Ford/MH 4x4's (or 4x6 as the case may be)?

Can somebody please breifly detail the differences in the F60 series model letters - L, S, H, etc?

Can somebody please briefly detail differences in the cab numbers - 11, 12, 13 etc?

Im am lead to beleive that the basic 158" wheelbase chassis (with only 4 wheels not 6) remianed the same from 40 to 45 with only cab changes - is that right?

I have searched the MLU website but i couldnt find the answers to these specific questions - (no offence Geoff )

Thanks (once again) in advance all.
Glenn.
