For whatever it is worth, the last year for Super Beetle sedans was 1975. The standard Beetles were made in Emden, Germany through 1978 although the last year they were imported into North America was 1977. (One of my favorite Beetles is the Last Edition made for the UK in '78.)
With any conversion you do, it takes planning. Feel free to search. Feel free to ask questions. To utilize Porsche wheels, you are going to change the bolt pattern. That will require making a choice on brakes. Those wheels will also make you choose your front end set-up and the tires you will want. It may even make you ponder on whether you want to keep the stock fenders or go wider.
There are many options. I am not as familiar with standards as I am with Supers so I will not offer one of my own. But plan everything together as they will have to fit with each other together. That means knowing what you already have such as the offset and dimensions of your wheels.
Good luck ... and welcome!
