911 headlights / lenses to -67 fenders, what parts fits and where to buy?

[-Alex-]

Dont know the advantages of H5 instead of H4..

But i think these porsche headlights are ok for northern summer use, we have much more light at summer months than southern europeans

But to be safe, i'll put Osram nightbreaker / Philips xtreme vision etc bright bulbs .
