The '97 serria I have has all of the little fold down cubbies on the headliner. Right below the two reading lamps is a blank panel about 4"-5" wide and mabey 1 1/2" tall. Would a compass have come there on another package. My trucks got the fulll load but its a 3/4 ton and I know sometimes the options are different from 1/2 tons. Would it be per-wired? If not a compass, then what goes there?
