No 1990 indoor attempt at 6.04, but here's a clearance of his over 5.60 - possibly from 1993.
https://www.youtube.com/watch?v=4OcdtlTyP2MI hope you can find his WR attempts on vid. A starting point might be to determine which US vaulters competed in Yokohama in 1990, then track it from there.
Does anybody know who competed there?
According to
http://www.trackandfieldnews.com/images/stories/Rankings/15-mpvrank.pdf, the 2 top Americans in 1990 were Tim Bright and Kory Tarpenning. Perhaps one of them might have some vid? Or at least remember who competed in Yokohama that year?
Incidentally, Grigoriy Yegorov was ranked 2nd that year.
