I've gone looking for some fresh hardware (screws, etc.) for the interior and all I can find is the garden variety #8 and #10 chrome screws which are not the correct size.

Has anyone found a source for metric interior screws, etc.?

online Automobile Atlanta has I think what you want. Their online catalog breaks out every nut and bolt by size and application. Mike

yes we have all of that as well as a complete hardware kit for the exterior and interior of the car all clearly labeled. I put it together myself sitting with the Wurth Winter guy for hours pouring over the original Porsche 914 factory parts books until I had every one. THEN had to identify the shape and size from my memory to make sure that they were correct. ( I did have fun doing it, comes in three organized plastic bins)

Bel Metric. You'll need to look up each in the PET manual for exact size before ordering.

I also have used BelMetric for a lot of the fasteners on my car.
Great products and normally super quick shipping/delivery.

But you do have to know the sizes you are looking for....
