Thanks guys for the response. I've booked it in at my local indie to get it sorted early new year as looks like it will need to get a rivet on it from the inside of the car to remount the bolt the strut normally sits on (its this part that has failed / sheered off. Can't no pics unfortunately as it took me a good 30mins in the pouring rain to get it closed so don't want to risk it. At least it didn't fall on my head!
Looks like an easy one to replace if it is only the strut you need.
