I replaced the six Torx drive M10 x 1.5mm x 22.5mm bolts holding down the plastic panels beneath the rear seats. The first time I had to remove these bolts, I had to press a Torx bit out of its 3/8" drive holder, then use a small ratchet to drive the tool from underneath the seat bars.
The new bolts are internal hex drive M10 x 1.5mm x 25mm with washers. Now I can install or remove the bolts with an Allen ball driver - much easier. I have to wonder why Ineos used such large fasteners (with thread locker!) here - a small screw with a fender washer would have worked quite well.
