You could try an agent here, maybe they would send them back, Apex in the Uk are a main distributed as far as I know, or maybe google BC and try email them direct
Was on to a place in uk that can service them or sell me new damper, these coilover have very small miles done and one is gone but have heard good things about them. I drove the car home only about 50 miles on good road so not sure what bc are like but wasn't as hard as other cars I have with Cusco coilovers. . I only tuck them out cause the roads arent great around here especially this time of year.
