there is one guy who I think i could point you too
he restores/builds classic VW's, he sources all his stuff from US clubs and meets
am not a VW expert so here's my best effort in describing the bugs he restores/builds
he has a top down fully restored (did i say that right?) (this the roadster?)
another rag top where you can slide the top all the way to the back
another one with the a split window (a sweeter??)
and a 1956 or is it 66 sedan convertible
