Seat frame picture needed

[nailzscott]

I have a 67 mgb with the seats being reupholstered. There are two screws on the back / bottom of the seat back that rest upon the bottom rail. Can anyone take a picture of this area and post or send it so that I can show my upholster guy what it is supposed to look like. He originally wrapped the upholstery around the bottom seat bar - but the screws are supposed to rest on that bar, and he cannot figure out what to do. Some pictures would be a great help.
