I stripped the threads on one of my lug bolts. The part number is 914 361 315 01 or 02. They are $25 each on Pelican! They are also pretty pricey on Ebay and other Porsche suppliers.
My FLAPS says they can get a set of 10 for around $65.
I searched around on this site and others and found a reference to this VW part number (thanks to @ClayPerrine ): 701 601 139B.
I found these two sources:
This site has other sizes. I'm not sure what the length in the description refers to; the OAL or the length of the threaded part. I need a minimum of 30 mm of thread. These are $1.74 each. I will contact them and see if they have any more details. The "fitment" says they don't fit a 914, but they look like the same bolt. I tried the fitment on several different sizes and they all "didn't fit".

This site has the VW ones for $1.46 each. The "fitment" says they don't fit a 914, but they look like the same bolt.

Does anyone have any experience using either of these on a 914? I have 4 lug Fuchs (probably repros, if that matters).
