I found a replica of a '40 ford hood that says it fits a beetle. I'm not sure if it fits a super beetle but if you're interested here's the link.
There is also a pair of suicide doors for a '73 superbeetle if you are interested. They are both listed on the same page.
I don't know how to insert a picture yet or else I would put one in.
I also just found a picture of a bug with the same hood on it. There are also other major modifications but I'm just looking at the front end. Here's that link
