Two more at the bottom, one is to the right of the lower "6" that molded into the bun, you can see where the fabric is being tugged at the rusty bar. Your second goes in the same place on the other side.
Now fold the bottom flap over and put in two more.
You are finished with the bottom's!!! You are probably going to need a few more to tie up the loose ends but these were enough for me.
Now for the upper back seat. Take all the old rings and pull the cover off like before. Lay the new cover out and set the old bun/frame on top.
Start working the cover on.
It should start to look like this.
Make sure everything is nice and tight and apply your first right in the middle of the transmission tunnel.
Two more.
Two more.
And two more, one on each corner. Each side should look like this with three rings at each end.
Now flip it over and put two as close as you can to the center. This is the top side now.
One in the middle, put another in the same place at the other end.
