I have a well traveled set of four painted crest caps for you folks or your fuchs. They were on my cookie cutters and have the distinction of having made it to San Simeon, San Francisco, San Jacinto, San Larmo, San D I go, and other places far and near. These caps have sneered at electric car dudes with smoking hot passenger-chicks longing for the smell of unburnt gas and tatty naugahyde over rotted wool interiors / all the good stuff of owning a 914.
If you have a hole to fill (much less 4 of them), this may be your only real sensible choice.
Four center caps shipped for 72.50 US bucks contus.
