For my RST build completed last year, I used Wurth metric yellow zinc plated almost exclusively for everything accept engine I have exactly 6 SAE fitting in my car, being the large hose clamps for the inter cooler. In Canada at least, Wurth delivers to your door. Packages come in 50,100,200 packages depending on size. Very cost effective. For those odd few items, like the fender bolts/gaskets as well as self taping screws I got directly from ou host.
Good luck.

I am always struggling to find hardware locally. Thanks to all that posted info.

Shaun, can't confirm that. The pieces that I ordered, using part numbers that I supplied to the parts dept, were smaller screws, washers etc that I don't believe have any head numbers or the such. Just the correct "looking" pieces for my interior.

Eagle Day has Porsche metric fastener kits and individual items as well.
