Is there any difference in body or length in bed besides short bed or long bed
to answer your question; the only major difference is that the C20 doesn't come in a short bed. everything else is interchangeable except(as mentioned previously) rear cab mounts. C20 rear cab mounts are not obtainable and the C10 ones will work with the addition of a C10 frame mount and they are obtainable after market.
