help with 68 300 center arm rest brackets

Can someone post a picture or tell me were the center arm rest bracket welds to the drive line tunnel floor. It looks like they weld behind the too humps on the tunnel. They may go in front of the humps. I do not think they mount on top of them. I know if someone has a 300 with the seats out they know what I'm talking about. Going from bench to buckets without center console.
