What Full size Chevy truck beds are interchangeable with one another?

I have a 1989 Chevy Silverado 1/2 ton and going to buy a used flatbed from an older truck which is early 80's my truck is a longbed and this flatbed is an 8 foot flatbed off a 3/4 ton. I just need to know if there may be a difference?|||that so called long bed is a 8 foot bed.... you may have to make your own mounting brackets....i dont know if the mounting points on both beds are the same or not|||Versa Collection Full/Queen Bedroom Set
