Hi Ricky.
Was it front or rear?
Shockers,ie, dampers should ideally be replaced in pairs,as the new one will be stronger than the old one still on the car.
Try ianp6man,he has a good stash of s/h and new spares.
They do crop up on ebay,fronts being pricey. "search P6 Shock."
Watch out for the front ones with metal inserts in the bush,thats not correct!!
