C : IT means two(2) wheel drive
K : IT means four (4) wheel drive
10 : IT means shortbed
20 : IT means longbed
30 : usually means dually(sold stock as chassis and cab, without a bed)

EXamples : C-10 =TWD shortbed
K-20= FWD longbed

most of you already know this, but this is for the ones that don't

10 is half ton
20 is 3/4 ton, and 30 is one ton.
A one ton could be had with single rear wheels also.

C/K10 is 1/2 ton and can be short or long bed. C/K20 is 3/4 ton, 30 is 1 ton.

Just wanted to weigh in and say posters #2, 3, and 4 are correct.

A couple additional comments:

The model code is different than the coding contained in the VIN

So, additionally, an "03" model is a regular cab truck, and a "43" is a bonus/crew cab.

The complete model code might look like:

CC10703 =
C = Chevrolet
C = 2wd
1 = 10 series, or 1/2 ton
07 = short wheel base
03 = regular cab

The box type would be a regular production option separate from the model code, ie:
E62 = fenderside
E63 = fleetside

A second example might be:

TK30943 =
T = GMC
K = 4wd
3 = 1 ton
09 = long wheel base
43 = crew or bonus cab

Single or dual rear wheels are an RPO on top of that, - R05 being single, +R05 being dual.

As the GMT400 truck was being developed the "R/V" designation was used to denote the carryover truck.

In later years a '53 model was an extended cab.

But - you guys probably already knew that!

in 67 - 72 the bed style was part of the model number, not an RPO.

**Thealien** · 10-09-2010, 05:38 PM

And to add another twist K5 can be 2 or 4 WD

Stupid hurts for a reason, it's trying to tell you something.

Learn from the mistakes of others, You won't live long enough to make them all yourself.

Thanks, Longhorn.

I probably should have mentioned my expertise is '73 -87.

I was just heading over to the SPID thread to brush up a bit on '67 -72...

(lol)

im down for someone showing me how to do it or helping me out. my sig. means that i learn to do my own stuff, and if i get it wrong, i fix it and do it right, rather than having some one else do my stuff for me all the time. it in no way is me trying to sound arrogant.
