Hello Jake. If your truck is indeed a C20 then the 6 1/2 ft. bed wasn't an option. It should have a 8 ft. bed with a wheel base [center of front hub to center of rear hub] of 127 in. Short beds were 115 in. Those are 1963 specs and I don't think they changed much between years. If your truck appears shorter then maybe the frame was swapped or shortened. Do you have 6 lugs or 8 lugs?
