Thanks for the warm welcome guys. Appreciated.
I think the diff is standard ... when funds allow I will look at uprating to a Quaife.
When the weather improves I will pop up the road to Northern Alfa for a service.
Then will get the teledials powder coated and rear bumper re sprayed as it has a few scratches, which whilst not severe, needs doing. Need to sort out the outer door seals as they seem to have come out of the runners... am struggling to pop them back in at the moment so will have a dig around the forum and see how others have addressed this problem.
