[The Aussie]

G'day all,
I'm wanting to know what the following models are:-K105(16) I understand K10 is 1/2 ton truck, &(16)is a two door utility. Am I correct, & what does the 5 stand for?

K107(53) & K109(53) K10 as above,& (53)is two door extended cab. Am I correct, & what does the 7, & the 9 stand for?

I ran this query in the Members Forum, & got some of the answers, but not the above.

Thanhs in advance.

This is from a GM parts book .

CK(03) = (Cab 2 Door)
CK(43) = (Cab 4 door)
CK(06) = (Suburban)
CK(16) = (Blazer , Jimmy)
RV(03) = (Cab 2 Door)
RV(43) = (Cab 4 Door)
RV(06) = (Suburban)
RV(16) = (Blazer , Jimmy)

C107 = 1/2 ton 6 1/2 FT bed 117.5 WB
C109 = 1/2 ton 8 FT bed 131.5 WB
C209 = 3/4 ton 8 FT bed 131.5 , 164.5 WB
C309 = 1 ton 8 FT bed 131.5 , 164.5 WB
C310 = 1 ton 2-door chassis-cab 135.5 WB
C314 = 1 ton 2-door chassis-cab 159.5 WB

This is just for the C series but the K and RV series is similiar . Then you add options on the end of these numbers and get even more ! So a C309 (43)+E63+AS3 is a 1 ton crew cab fleetside/wideside w/8 FT bed on 164.5 WB while a C309 (43)+ZW9+AS3+C7C is a crew cab chassis-cab on a 164.5 WB .
