I presently have my 693 alternator in for restoration. When discussing the broadcast code, I stated that I believe it should be NL based on posts in this and other forums. I was told with certainty that the broadcast code is CB. So, I looked into it further and did find restored alternators being sold with a CB stamp as well as some photos of well-known 67 Z-28's with CB stamped alternators.
Could the issue be that CB is the broadcast code for one of the higher amp alternators?
Hoping that someone with a Chassis Broadcast Copy (production alternator) can set me straight. Cheers
I think CB is the pulley. NL is the alternator.
