This is how the 2nd spare is mounted.
A strap (masking tape) runs through the centre and around the wheel. The chain is looped under the strap and that has a shackle through it.
I’m going to thread the crane cable through the chain and then secure the cable into its hook assembly so the crane cable and the crane boom will help secure the spare as well the centre bolt that is holding it.
MENG bolt head to be painted that holds the securing centre bolt.
And now the crane is fitted. Just letting the base fully cure as I need to use a bit pressure to make sure the boom pushes against the wheel.
I decided to go heavy with the wear and tear on the crane as it would be a real work horse.
