'68 fenders on a '71 superbeetle?

[oasis]

When I read the question the first time, I assumed it was about the rear fenders only. That way, one could get earlier taillights on their Super. (In the US, the taillights went larger for 1971 and 1972.) Swapping for 1968-70 rear fenders would be easy.

A 1968-specific front fender would still have the upright headlamp, so I don't see the reason for wanting it over a '71 Super front fender. The only difference -- a big difference at that -- is the '68 fender would be shorter. Even if shorter front fenders were somehow fabricated to work, the longer hood would be even more pronounced.

To get pre-1967 headlamps, Creative Car Craft makes fiberglass fenders for that. You can only get them as wider than stock, however.
