The dart was my dad's daily driver, he put 300,000 miles on it in 25 years
Man, That's cool as can be! Awesome! Ok, went out to the car. Hard to get an Exact # with everything in the way, and not using a square or 2 levels for reference, plus it's dark here. About 7. 125 or a .25@ crank and 6 to 6 and an 1/8 th or 1/4" for WP...was running a flex fan, switched to a clutch set up, supplied by some Good Mopar Brothers here. Haven't put the clutch set up in traffic in summer yet...
