I'm astonished that they would have another name for this color code. It has me a bit concerned what I will get when I go to fill my paint order when I eventually reach the point when I am painting. The 1968 GM color names for Ditzler 71634 were:

Chevy-Matador Red
Pontiac - Solar Red
Buick - Scarlet Red
Olds - Scarlet

I looked on autocolorlibrary.com at similar years and GM makes and whatnot and I don't find a Tobasco described anywhere. I'm not sure it matters, especially if it crossed over.

What counts in the end is not the paint name but how it looks when you're finished. Have you opened the can to see what is inside? I hope it looks great. I hope your paint turns out awesome.
