Hi, my 203 & 403 have some up/down movement questioned by our Warrant of fitness tests. The parts manual quotes the upper shim as 24x36x2mm. Does anybody know re availability of these or alternatives. I notice they are made of some non metal "fabric". Our 6 monthly WOF system is getting a tickle up at the moment because some dodgy garages have been taking short cuts so slight movement in this area freaks them out......crow bar under the tyre "test"!! Many thanks Dave DUIRS
