Is the picture of your old flywheel showing the starter side of the ring gear?
Yes it is, as per your request.
Yes mine was CNC'd. I have slightly lighter one but the machining went into the ring gear by about 3 mm and I don't know if it'll hold up. My machinist did exactly as I asked, I just asked for a bit too much.
It'll make a great lamp base eventually.
