I don't know if you have this info, but I found it in a SCCA Sports Car magazine May 1972. Bogota, Columbia, Feb. 27, 1972 = Two Heats = #1
Syd Demovsky/Chicago, Illinois 11th place; Jim Harrell/Tecumseh, Michigan 16th place (spun). #2 Syd = 13th place, Jim 19th (hole in oil pan)
. Will send more soon. Ken.
