Thought I would show what happens when you order new parts from Porsche. Both are the same part with the difference of manufacture date and the later one has version 04 on the end. The original one has a raw nut and green tubing 2013 version. The second version has yellow zinc fitting and black tubing 2018 version. Both are OEM Porsche parts. The old question which one is correct for restoration?

Probably a permutation of that part that's is NLA

My '74 has all green tubing.
