Rodriguez or Siffert?

Mexican Pedro Rodriguez (picture above) and Swiss ace Jo Siffert were the lead drivers in the JWA Gulf Porsche endurance squad in 1970. Unusual: Pedro Rodriguez tries to amuse the public present by ‘stealing’ Jo Siffert’s helmet, at a Porsche event held at Hockenheim in 1970. The two drivers were friends, but it didn’t prevent them to fight hard on track, like here-below, at the start of the 1970 1000 km of Spa.
