1961 NHRA Nationals

I just watched a youtube video about the 1961 NHRA Nationals. Toward the end of the video when they were presenting winner's trophies, one of the winners was Junior Johnson. I didn't know he drag raced. I did a search and couldn't find anything other than NASCAR history on him. Also, there was a rail with "dual wheels," there was no mention of the driver, but I remember Garletts showing up to race with a dual wheel dragster. Tommy IVO ran his four-engine rail, strange seeing it in the film, I thought Ivo came out with that dragster later than 61. quite an interesting video though.
