well i currently am stationed in england, no scions let alone xb here, and i need to pass the MOT here. my question is( and yes i have searched) are toyota yaris parts interchangeable with the xbs? i just need some rear shocks and i only have ten working days to get this resolved.... thanks for the help guys

according to rockauto there shock is unique to the xb/xa. I'd suggest removing one of the rear shocks and taking it to an auto parts store. They should be able to compare it to other shocks til they find one that will fit.
