#57 Bobby Brack
Based out of the Hialeah Speedway, or at least I saw him run there. Maybe also at the GuvCup at Golden Gate.
Everybody at Hialeah (including the sharp looking ladies in the stands) was as tough as nails.
My recollection is that along with Larry Rogero and Gary Balough, Brack was among the toughest.
Note the more-businesslike-than-most front bumper.
