In my search for a replacement center cap for my Fuchs I stumbled across this vendor. He was the original manufacturer of the rare part I was looking for. Ralph is a very nice, friendly, helpful guy. The part I need is an out of stock, discontinued item, but he was still able to find one for me.
He makes a few 914 specific items like center caps for 2 liter Fuchs alloys, spacers and 5 lug adapters plus a number of other licensed Porsche crested items. Check out his web site at http://boothedesign.com/.
