Very nice mate, got a good looking frame to start on.
Though I would like to see it being restored to an original look. I had a 72 bug that was Cal look, the wife had a 76 model Superbeetle, and the father in law recently sold his 69 Karmann Cabrio that was restored too.
But really do think that with the oval rears being quite rare that these should be done the way they came out of the factory (of cause that is just my opinion, but could eaily buy a cheap nice model if you just wanted to soup it up for the tracks)
