Todd,    Speaking of your PM alternator installation do you have any updates to report ?...... --

Hi Dave;
    When I disassembled my plate to install the PM generator rotor cup, I did notice a couple of minor smoke trails from a few of the rivets, However when I drilled them out for disassembly, none of them spun with the drill bit, indicating that they were still tight. Since this is something that I've modified from the original design, I'll certainly pay close attention to it now.
