I have a set of Tein HAs on my drift Silvia, and one of them has died

. There is now play i the shaft which is really not good on a car with McPherson struts, as the wheels can now move too. Avoiding the long stories about the dodgy importer and my missing Cusco dampers, I need to get these fixed asap so I can get to more events and the much needed practice.
Does anyone know where I can get them rebuilt? or if there is play in the shafts on a strut, are they just too far gone?
