How to understand assembly manual model designations?

[davepl]

In the assembly manual there are often differentiations in instructions by model, but I'm not 100% sure I understand how to read them.

Usually there is a prefix (C, K, M, CA, KA, SA) and a postfix (100, 200, 300, 400,500, 600). I would guess that C and K are 2WD and 4WD, and my first thought was that 100=1/2 ton, 200=3/4 ton and so on, but what's with the 400/500/600? I don't think the assembly manual covers the medium duty trucks.

I also don't know what the difference between C and CA (or K and KA for that matter) is.

On my SPID my truck is a CE26034, which other than the "C" part doesn't map to much.

Could someone who knows chime on how to read them, or point me

Dave, You are on the right track. Here I will try to break down some of the more relevant designations for you.
C= Conventional cab trucks, like our pickups.
K= Conventional 4X4 applications
CA= Is simply Conventional all but may be range limited like 10-30
KA= Again all 4X4s
CS or KS would be conventional trucks with an I6 engine
CE or KE would be conventional trucks with a V8.
G vehicles are the classic Chevy vans and may be seen in GA GS GE as well.
P series or PA are the boxy forward control step vans
DD is another step van
MH is the motor-home chassis (think drivable frame here)
10-90/1500-9500 are series designations related to the GVW range. For our purposes 10-30/1500-3500 rated at 3900-14,000 lbs GVW are of mos interest.
However often parts from other ranges and models carry over. The air pressure and vacuum gages come to mind as Med duty 40-60 parts that are a popular fit in pickups and assemble pretty much the same way. There is a LOT more to this but this should help.

Sorry meant to address this as well and keep it simple.
CE26034
C conventional 4x2 series 10-60
E V8 gasoline engine
2 5200-7500 GVW
60 cab to rear axle dimension (rounded)
34 fleetside pickup bed

Thanks very much, that's great info. What about the 100/200/300/400/500/600? Is it as simple as C10, C20, C30, C40, C50 and C60 (for a C model, anyway) or is it more complicated?

Yes, Things can get a little blury like a C30 with 11k rear but overall where you are and what you are doing it will work for you.
