What I'm going to do is make the #2 version decal, with it saying: "One of 4118", and then include in smaller type-- 3867 CS, 251 HCS. I gave this a lot of thought, and have made this decision.
The reason is that the original engineering and development of the "California Mustang" produced 4,118 of these units.
In the eyes of Ford, Kevin Marti, and the publications of the day in 1968, it was primarily a GT/CS, so the historical context is why I'm going with this decision.
So, in that context, I'll go with the total number. There are other DSOs that got equal, if not more cars than the Denver district did. It's just that the Denver dealers wanted to add some badging to their allotment. Any other DSO could have done the same thing (Texas wanted their own Special). Arizona got a lot more cars than Denver. Unlike the '66 and '67 versions of the HCS, the '68 version was not a pre-destined Mustang variant, and was not really an idea from Dearborn.
I don't mean to sound indifferent to the HCS folks, but in a practical "big picture" production standpoint, I'll go with the overall number. I'm still aknowledging the HCS number on the decal, tho'.
I'll look into doing a small run of HCS-only decals.
Thanks for your input,
