You talking about the 1967/68 Green Monster which was used by Slick Gardner in 1975.
Would be great if this racer found now a public museum place, after it stand for years in a sheet of Slick Gardner's farm close to Buellton, CA.
By the way, this is not the record breaker Green Monster from 64/65 - this one was destroyed by a record attempt in 1966, when a bearing failed by 620 mph....
