This is Sebring, 1963.
Roger Penske (250GTO, #24) is ahead of David Piper's GTO, and Dave MacDonald/Fireball Roberts trail in CSX2026
(A bit of useless but vaguely interesting information ....Penske's GTO is blue, and Piper's GTO is - (as always with his cars) green.
Penske's 250GTO finished 4th
Piper/Cantrell's 250GTO finished 14th
The MacDonald/Roberts' Cobra blew a diff and DNF'd, but Ken Miles/Phil Hill/Lew Spencer's Cobra finished 11th outright and 1st in the GT, 4 litre+ class
Cheers,
Glen
