Big, Bad*s*, and ugly 660L

The sockets came in today and now I have a life time supply of six pinners. Some came with the metal mounting bracket and other with just the snap ring. If I'm really lucky the hole in the chassis with be just the right size that I can mount with just the snap ring, but I'm not holding my breath!
I guess I have no excuse now not to work on it. I found a capacitance calculator on line and determined that my quick calculation of 182 mmfd was way off. It should be closer to 500 mmfd. I'm glad I found this out else I'd be doing the trial and error thing a lot longer.
