John,
The ones I got from vw looked like brass and were
about 50 cents a piece. I bought a bakers dozen to
get a free one as my vw man has a sense of humor and
redwood city vw serves coffee and doughnuts at their
parts place. I just asked them for some generic
exhaust bolts which were made of the newer alloys.
He had two styles of self locking nuts. Doughnuts
were good too. gary
