you should be able to get a new woodruff key. a air impact w/ a six point socket makes it easy to remove since i think the flywheel bolts are tightened to 110 ft lbs on a 292( i think the other engines are only 60 or 65 i don't know why). you can use a tool that holds the teeth on the flywheel and take off with a breaker bar. when the spline starts to enter the clutch and stops i have had good luck with turning the engine in small amounts till i feel it start to engage and slide it on in. the last one i put in was the first i did with a new pilot bushing and the clutch had to be lined up perfect. i had to use a old mainshaft instead of the plastic tool because the plastic tool wasn't as tight a fit. i had just learned this from a old post. good luck, hoggyrubber
