Ford really wasn't "in" racing in '59 so when some '59 T-birds left out the back door, in pieces at scrap prices, headed for the Douglas Municipal airport in Charlotte NC some guys in Dearborn had to make themselves mighty scarce around the watercooler for a while until the dust settled.
Holman Moody built some turnkey racers out of them and former GM driver Cotton Owens wound up with one of the potent 430 cubic inch Lincoln powered cars that looked sorta like this. Cotton made both the Grand National and Convertible Division races in his "Thunderchick" but didn't get GN points for the races he ran in without a rear window to make the removable top easier to deal with.
