Well, I know that my dad's came with balck chrome tips, it was part of what made him buy the car. You can believe me or not, I really don't care.
I know you are offeneded by what is said here, but the bottom line is that I have alot of information here from Pontiac fro dealer manuals, to order sheets, to build sheets, to Pontiac Dealer bulletins, and more. And in not ONE of them is there EVER a mention of black chrome tips. Ever. The only mention of black chrome tips is on the first 8 1976 50th Anniversaries in 1976. That is all. And I will stick to that until I can be proven otherwise with some sort of proof that GM and Pontiac did black chrome tips. I have had arguments all the time about different things with original owners of cars about what was on their car brand new. Alot of people get confused about what was Factory installed and what might have been Dealer installed. So, I am not saying your dad's car did not come with them, what I am saying is that they were not a Factory option that I have ever found. If someone can prove proof that they existed, then I would be more than happy to do a full apology to anyone I have ever conversed with on this subject.
Too many know it all TA "experts" around. If they haven't seen it, it never exosted.
I know that you are upset with some here and I have never claimed to be an "Expert", just a "Specialist". And I also do not believe in ghosts, UFO's or Bigfoot. I have never seen any of them and none can provide conclusive proof that any of them exist.
