You havent given us enough detail. When you say 'Bottom Spring" do you mean the mattress support?
The drop down bars bolt on to the headboard or footboard (one each) and let the dropside move up and down, held in place by the bars. The backside usually has bolts that run thru the head and footboard
to attach them. Some just have small nubs that the top of the backside sit onto and a bolt holds the
bottom of both sides. If you wish to send a picture of what you have for further details, send
it to

I will help you get it right.
