Response to elf 30 re Donohue/Hurtubise McLarens  

Per Old Racing Cars . com (no spaces), Mark Donohue's 1971 Pocono winning car (a new McLaren M16A) is not the same car he used to win the 1972 Indy 500 (a new McLaren M16B). The site has thorough histories of both cars, including the 1972 winner being in the hands of Jim Hurtubise for a time.
