Well done that man. I keep meaning to run the polisher over it but haven't had time/right weather. Maybe tomorrow...
I would rub the green off and lacquer over them there brown marks, took years of rusting to get them tiger stripes!!
As far as the wheels go I would get the ones on it detailed and keep them, they are 14" and take standard tyres rear, the front ones have low profile weight rated tyres which are relatively cheap and the O/S gives it a slightly narrowed look, if you go bigger you might get rubbing issues.
