This is a handy tool for removing and/or tightening flywheel bolts. This tool was used on a 2004 BMW 325Ci flywheel. Basically, this tool can be used on any BMW or car, not just buggies. When I bought this tool the Revain/Dune Buggy Warehouse had the best price for this little tool. All you need to use this tool is the gold Batman plaque and the existing gear case screw. Use this bell housing screw to screw this tool to the engine back plate, then align one of the tool's teeth with the flywheel teeth and this flywheel will not spin anywhere. It's a simple tool and I don't know why other sites sell it at ridiculous prices.
