Looks like angle plug heads to me, and it's # 438 page 22 on mine too. The first time I saw Beswick run on a dragstrip I was 18 years old in 71, it was with the 71 hemi challenger in Ohio, at Thompson Dragraceway, with the Coca Cola Cavalcade of stars. After years of gleaning over magazine articles about his Pontiacs as a kid, I was none too happy to see him wheeling a mopar product. I guess he hadda make a living, and at the time Pontiac had dried up as far as parts that could be used in a funny car and still be competitive. I don't recall where he ended up that night, but I do know he didn't win the race, I still wasn't happy though.
