Ok, I was milling through the 84 and 85 parts books, looking at decals for Daytona Turbos. I noticed something strange.
Although not listed in the 1985 Brochure, the parts diagrams show decals for a PW2 Daytona Turbo. White. The decals have white centers in 'turbo'. Then I went back and looked at some Google images of Daytona Turbos, and the ones I formerly thought were a very light silver are actually white. So they do exist.
Just sharing some interesting-to-me knowledge since all along I have trusted that brochure.
