Boot lock, rear seat belts, rear seat retainers

I'm after a genuine boot lock with key, the rear seat belt buckles that bolt into the floor including bolts etc. I may take a complete set of belts and buckles if its all that's available.

Also I need whatever goes on to retain the rear seats to the body. I've got the rods on the seats that fit over the nipples on the body but I need whatever holds them on. The car I bought just had the rear seat placed in so I'm not sure what I'm after?

Cheers
