harmonic balancer puller has the exact size bolts and does the trick. i use a impact to remove the flywheel bolt then turn the impact down to low setting and hand tighten the balancer puller on and then allow the impact to just tap the main bolt a little at a time then the flywheel comes off. SIDE NOTE. do not put the 3 screws into the flywheel to much. there is a very key electrical component behind the flywheel that you will hit if the 3 anchor bolts are screwed in to much.
this happened to me and i got a new bendix and i still soaked it in atf before installing.
