Thanks for that information.I did think this maybe the case,that why I thought I would refer to the forum.
I bought the stems ,rubbers and grabrail from DS(US spec) but they didn't appear to have the plates.I have found a Company in the States(4into1)on the net they have them $46.00 DHL deliverd .don't know if this is a good bet?
I think I might have go at making my own?how hard can it be to cut ,shape,drill two holes tack/weld a nut on and paint black. the earth I can run from inside the indicator it's self.
