I use a machine shop to machine the LH 2.2 flywheels to work with the pickup for a LH2.4. Also can do the flat flywheels from earlier model B23/B230 engines. So far the testing is almost complete though the mount for the 2.4 pickup on the back of the block will need to be shaved a couple of mm to move the sensor closer to the block.
Finding a genuine flywheel will be tough, there are not many around.
Plan is to get out there this week to get another one or two machined, it has been about a year since last on this project, life and work gets in the way...
