Hi Steve, There are special sockets in the market that will do the job. If you go to a good tools specialist, they will help you or tell you where to buy the socket or you may be able to borrow it by leaving a deposit.
Have you asked any of your local garages?
This socket looks like any normal socket, only differrence is it has metal pins inside.
Good luck Steve
