Anyone know of video online or on DVD of the redesigned kidney shaped track at Trenton from 69 to 72 when the Grand Nationals raced there? In 1969 it went from a 1 mile track to a 1.5 mile track with a doglegin it. The "Northern 300" date was replaced with Pocono in 1974. 73 was rained out and not run. Petty won twice and Allison and Pearson won the other times.
