recliner spring replacement?

Ok, so I have a mid 90's recliner. It swivels, glides and reclines. This has been a great peice to have been used nearly everyday since i purchased it new. The spring for the recilner has broken. I have retrieved a spring from the local furniture store that matches in length. I cannot figure out how the spring mounts in to the assembly. I have guessed at it with no prevale!!! Can someone explain to me how it goes in place? A picture diagram would be great, if that is possible. THANK YOU!!!
