I can't take credit for finding the articles, but here are a couple from "less well known" sources:
https://www.texasmonthly.com/the-culture/ford-v-ferrari-carroll-shelby-dallas/
https://www.motoringresearch.com/car-news/features/ford-vs-ferrari-gt40-le-mans/
also great period photos - including one of those Transporters - in ^^^ this article.
Great articles. Thanks for posting!
I'm glad that they are of interest.
I must admit that I didn't know there even was a Texas Monthly magazine ::)
