ya its a link pin. On the uppers, one has the VW symbol with a 54 beside it and a \"19 R\", the other upper has a VW symbol with a 32 beside it and \"S 19\". The lower arms have VW 4 and 12M, the other lower has VW 7 and 12H. I dont know what these number mean if any one does I would be interested.
Thanks.
