Having removed the spare wheel and replacing with some Holtz, I'd like to remove the plastic threadded spindle in the centre of the spare wheel well and create a removable bag/lining to increase the boot space. However, the plastic spindle appears to be fixed into the boot and not removable. There is a thicker collar which unscrews completely, but the spindle is 'hooked' under a metal lip in the boot floor. I'd preffer not to snap it off if possible so that it can be put back at a later date. Does anyone know how to take this out without breaking it?
