tailgate tear

I had another crazy thought of putting a tear in the bed of an old truck like a 5 window chevy or something with a long bed. See my family owns a car lot and we have cars that are old and new. If I want an old one I just ask. I would like an old chevy to fix up and put it in. My idea is put the tear in the bed for good or make it like those ones that have legs that can be put on and jacked out of the bed for use. I dont know, please tell me if this sounds ok or not, it sounds ok to me, thanks!
