[Mgs] MGB Visor and windshield center rod rivets

[PaulHunt73]

Short of an OE rivet if there's not enough room for the rubber to deform by 
the amount of the mushroom of a replacement then I'd be seeing whether there 
was scope to drill out the hole a little from the back so at least part of 
the mushroom sat in that.
