Friends,

people interested in actual provenance documentation should take a look at this FS thread:

http://www.early911sregistry.org/for...ern-Knob-65-66

the ad is for a '65-'66 plain/round shift knob, but the ad appears to include an actual piece of Porsche factory documentation that states that 'after March 21, 1967, cars will be shipped with the shift knob with the clear plastic shift pattern.'

we have lots of discussions about provenance in this community, but pieces of actual factory documentation are really cool.
