'68 Nova Quarter window channels - chrome bead or black?

[DougsL78]

Hi All,

Need to get a set of quarter window channels, guides, hardware for my '68 Nova L78 resto. The car has none of that when I bought it.

There are 2 flavors of this part available from several vendors - with chrome bead and without the chrome (all black). How do I determine what is correct for my car? The car originally has no window chrome on the exterior - but I don't think the chrome/no chrome bead on the channels is tied to that trim option...

This is the next adventure - deciding which vendor has the most correct parts for functional quarter windows - there are old threads that that reproduction guides sucked - but hoping that in the last 10 years the product(s) are better than they were back then.

Thanks in advance for your collective help.
