R/V body or C/K?
Throwing us a bone and a little more info would help. Plenty of us would be willing to help but you didn't really give us enough info here.
Stuff like 2wd or 4wd there were the two bodies that year so a truck would be a C or K a Crew cab would be a R /V body.
Believe it or not Autozone can probably get both and about as cheap as you get. I know they can get them on the 1/2 ton3/4 ton trucks on the R/V styles.

Some parts of the country you want Kragen but my understanding is both are owned by the same corp.
