-6 originality question, Front shock tar. Some with and some not? Options

[mountainroads]

A local shop is busy fixing some of the "work" that another local shop performed. I'm not happy about having to do that. PM me for details, if you want more info.

Although no concours or originality queen, I asked the shop owner if he could smear some of that undercoating/tar around the front shock towers while the car was in his shop, since that is supposed to be one of the defining characteristics of a -6. He said no problem, he'd look into it.

He called back the other day and said: "I looked at my car and it doesn't have what you describe. Happy to do it, but are you sure and can you send me a pic?" I asked if he was certain the stuff hadn't been removed at some point and he said he was positive. I've seen his car. It's a 40K mile, original paint, unmolested survivor. I have no reason to doubt either his expertise or knowledge of the car's history.

So..., is it possible that some sixes left the factory without that stuff? Yes, I already looked in the -6 originality and front trunk threads here and couldn't find a picture or definitive answer. Input on subject and if someone could post a pic, it would greatly appreciated. Also, cad or zinc-plated mounting hardware? TIA.
