I'm having a bit of trouble getting my flywheel off. I've seen flywheels with two holes on the front. I understand these holes are for a tool that immobilizes the flywheel. Now, my problem lies with these holes. My flywheel don't have holes on the front. There are two holes on the outside. I don't know of any tool that will adapt to my flywheel. All I have to work on is an impact wrench and a strap wrench. Any alternatives?
