Changing from one piece rear seats to 60:40 splits help.

Hi all, managed to fathem out how to change the rear seats over with the use of a old thread.

Now the only concern i've got now, is that the rear seats dont actually click down at the front edge of the seats. Mainly down to the clips in the body appear to be smaller, does the 60:40 bottoms require larger clips in the body?

If so are these readily available from skoda, the interior was out of a estate version.
