slack adjuster

Now I really need the slack adjuster ah, if not for the slack adjuster so I really don’t know where to find it! My things are now ready. But still a slack adjuster, I know the overseas import things is very difficult to buy accessories in the domestic, but even so I also find a lot of shops but they give me the results are the same, the configuration of slack adjuster is really very rare! I was very uncomfortable, I also have no way, I wish I can make my overseas friends to help me buy such a slack adjuster if it is really good!
