Hi all , my name is michelle and we have recently purchased a 2004 eura mobile activa 770hs , being newbies , we are having difficulties in finding the correct shocks for our vehicle , I have tried looking for the currant serial numbers but I am having no luck . I know its an alko chassis, twin wheel base , and we need 8000 shocks. Is there anybody that can give me any advice , or know the serial numbers we need .
