Exchanging hubs - ball joint fixing hole to big

Hi everyone!

Sorry, not really an Exige question but I thought someone here might be able to help?

Couple of years ago I was involved in an accident and the garage replaced one of my Ali rear hubs with a steel one.

I’m curruntly upgrading my suspension and am fitting uniball toe-links so I wanted to replace the Ali hub on the other side.

I’ve managed to get hold of a steel hub off a 340R, only thing is that I’ve just gone to bolt the new hub to the ball joint and the hole is bigger than the hole on the other hub. Apparently Elises/Exiges/340R’s all use the same ball joints. So I’m wondering if I need some sort of reducing shim?

Anyone come across this before?

Thanks for any help

Dave
