110 rear seats installation

[dingopup]

Hi everyone, my son recently purchased a 110 wagon that had the rear seats removed to make it into a camper, he has just purchased rear seats but when we went to install them found nothing attached to the body to bolt the brackets to. Anyone know what backing plates are supposed to be there if any? the sheet aluminium looks too light for the brackets to just bolt straight to it.
Cheers

The seats behind the front seats have brackets that are bolted through to mounts on the chassis.Photo is of passenger side mount.

Thanks Eddy, I can see it will be a 2 person job. Will need to get new bolta as the seats did not come with any.
