Carrera Panamericana Information Wanted

Contributor Stephen Mitchell has plans for a documentary on the original Carrera Panamericana races (!) and would like to tap the Sports Car Digest readers for information on the epic event.
From Stephen Mitchell:
I have begun work on a documentary project about the Carrera Panamericana road races held in Mexico from 1950-55. These five-day races were colorful, fast and dangerous–perhaps the most dangerous in the world–and required extraordinary skill and bravery on the part of the drivers just to survive the ordeal.
In addition to original footage shot during the race, I am interviewing people who were there or have standing to comment and offer perspective on these historic races. If you know of anyone who should be included in this document of an extraordinary competition, please let me know or have them contact me.
