Another member posted a pic of this badge asking about availability, then a few days later it popped up on my evil-bay 914 Parts search email, so I got one & it looks very nice & is a heavy casting about 3" diameter.
No affiliation, but I wanted to have mine in had to see it, before recommending it here.
About $55 with shipping to the USA from Germany.

You may want to add some clear or black nylon washers between the badge/screw/nut & your grill to avoid scratching, or perhaps substitute the Porsche all black rubber or rubber+metal Speed Nuts as used on the grill letters, 914, 1.7, 1.8, 2.0 & Porsche Crest Badges.
Cheers!
