ok so im about to bring this shop manual down to the frame guys who are gona fix the frame, but in the manual under the frame section with all the measurements they dont just have measurements for c10 they have it for c14 and c15. all i know is that mine is a short bed fleet side chevy c10, and it has the custom trim/cab. so if someone could let me know which one to tell them to look at (c14 or c15) id appreciate it. thanks.
