what i got?

I'm not sure exactly when the naming convention was changed, but I'll answer as best I can.

Earlier models (up till 1987) used the C and K designations for 2wd and

Later it was changed to R and V for 2wd and 4wd respectively, and the weight capacity was listed as 1500, 2500, and 3500 for 1/2, 3/4, and 1 ton.

So your 1984 4x4 truck (provided that it's a half ton) would be a K10. If it were a 1989 model for example, it should be a V1500. Same thing, different naming scheme.

This document pertains to Blazers, but should help explain some of this:

Actually, I typed first, and re-read that document later... Read the document at the provided link.

It's not a uniform system for all Chevy truck after 1987... However, your 1984 is a K10.

K-10 Is a Chevy 1/2 ton 4x4. K-15 is a GMC 1/2 4x4. Charles

R/V chassis went from 1988 to 1991. They were the designator for the older style trucks in production at that point with the new line of C/K trucks out. Charles

Ahhh long beat me to it, oh well.
