overhead air for front and rear. ????

[56HOTRODDER]

I went to look at a parts burb yesterday. The body is shot but its a standard trans 4 wd . ac truck with buckets and a tach all verified by the spid. What was unusual to me was the dash had no vents in the dash. the ac front and rear was all overhead. any thoughts? I have no interest in the accessories ;air cond or buckets. my interest is in the running gear and frame. i was puzzled by the ac setup. Was it factory or dealer installed? this is not a sales post , just wondering if there is much demand for those things. Thanks
