I bought a queen bed modification plate set online to connect a double bed headboard to fit onto our queen size bed and I can't seem to figure out how to make it work....  I spent $16.95 on the hardware.

It's been too long since I made the purchase (Jan 2012) and the company won't accept my return without charging me a restocking fee...  

Anyone interested in buying this from me?
