So I'm thinking on trading my 01 CCSB for a 97 CCSB. Both are 4x4 and my 01 has 203k and the 97 has 123k. They guy said my truck for his and 2 grand. It's a really clean truck but I don't know what's the difference between the 2 body styles. What I do know is that the fuel systems are different and that's about it. Any help would be great. Thanks guy.
