With the spares service on hold I am trying to sort my MK3 Forks I have sourced the seals using the alternative VS40 suggested on here (via search) but now I am looking for a replacement washer at the bottom of the Radraulic forks the parts list says C&A washer 31356 (although all mine are solid copper and in poor condition) but copper washers on the net seem to stall at 42mm I am wondering if there was an head exhaust washer from another bike that someone has used? alternatively I could turn a 1.75 ID 2.0 OD alloy washer about 1/16" thick and anneal it. all suggestions welcome
