I called Coy's and they said they're 9.5" definately won't fit a stock well which confused me since so many dudes run 9.5's in stock wells with no problems.

both traditional (stepped lip) and "fat-lip/smooth-lip/reverse mount" measure the same exact way.
9.5" torque thrust 2 measures 10.5" overall.
9.5" OEM c-5 vette wheel measures 10.5" overall
9.5" fat-lip coy's measures... wait for it... 10.5" overall
the correct backspacing or offset is what is going to make these wheels fit in your wheel wells.
bottom line, it has been proven that a 9.5" wheel w/5.5" backspace will work in the rear of a 1st Gen F-body.
