Topic: 70 Boss 302 Alternator spacer - Gold or Silver?

[rmaginnis]

2012 judging sheet state 70 Boss 302 has 'gold' finish spacer (between alternator and head).
really?
I have the original spacer and no gold anywhere on it, even on the inside looking down the hole of through the slot.  Mine is from Detroit, April build.  Attending many shows over the years and reviewing gobs of engine compartment pictures I have seen both silver and gold spacers.  Problem is most have been replaced from sources such as NPD and AMK.   
What is the source of the spacer data? I'd love to see a picture of a Perkins unmolested original 70 boss 302 alternator and spacer would help set the record straight.
Thanks,
Rick
