Steve McQueen has not done "reasonably well" for about 15 years; seems he fought a losing battle with mesothelioma, a disease that the CDC had never previously documented in a non-asbestos worker related diagnosis; they offered, by way of apology a tentative link to the scuffed-off asbestos from brake linings due mostly to his penchant for off-road dirtbike racing and roughing and occasional forays into auto racing. Didn't stick then, doesn't now, but funding is always important at budget time.
By the way, the Mustang front suspension had to be rebuilt after every take, while the Dodge never even fatgued either torsion bar; McQueen was a superior driver and a dedicated daredevil, but in the end, the Devil got his due.
Did you ever see McQueen in "ON ANY SUNDAY" by Bruce Brown. Browm did the movie "ENDLESS SUMMER" also. The first one was about some pals on motor cycles and the other was about surfers looking for the perfect wave. Both are classics.
