There is a new Brushless Alternator that comes on sooner than the Omega/Bosch Alternator. I think it is rated at a slightly higher amperage than the Omega. This is if you are happy with your stock ignition and are not going to need the Omega Crankshaft fired ignition. It requires the Bosch Alternator housing to mount.
The Brush less Alternator will also work when the GEN light bulb burns out.
