on the backs there is a bracket at the rear that I need to get the corresponding bracket to fit into the cappings, then at the front there is just a tongue that locates under the cappings.
As far as I can tell that are too long to fold up, the bottom would clash with the seat back on the second row.
In the pic attached there seems to be spacers at the front? I think this is to take up the difference in floor/bracket height.
