Spare wheel

[Deanno]

I'm hopefully going to start my car soon well if i sell my kayak on ebay

I'm thinking of mounting a spare wheel as WHEN i complete the car i intend to use it as an everyday car. and as i live in the sticks it would be nice to have a spare.

a bit like the design i have seen on ebay: 290457786970.

does anybody know what i would need to do regarding size, SVA etc?

Cheers Dean
