Steering wheel lock help

[Turbokid89]

Sorry if this sounds stupid but have a question as never had one before

Well forks have found a disklok steering wheel lock and am just wondering if it will fit/work on my car the steering wheel is 34cms but the lock says fits 39cms will this do or will I have to get a smaller one

Thanks

39cm is the small version. There's a bit of adjustment in them
