Sub Frame Connectors after Interior is finished

Weld the ends of the frame connecter to the frames and then use a bonding material to bind them to the floor. A lot of body shops will bond sheet metal together. Can't you just tack them to the floor and use something with an epoxy based to bond them to the floor?

This is what I was originally thinking. Was to weld up the ends and then do some tacks along the floor. I think I will just remove the deadener in those areas to be safe.
