Hi everybody I'm interested in making some car wheel arch trims from carbon fibre, the fronts are easy but what I cant work out is how to create the locating pins and clips on the rear of the part has they have to be 10th's of a mm precision.
Can anyone give me an idea of how this would be done please.

I 'm planning on a mold and not skinning if that helps

Just starting out so please take it easy on me, pre-thanks for any answers as I know time is precious these days :-)
