I finished the air cleaner on Friday by making a flange to mount it to the firewall and a clamp and brace. I had to modify my original design because I couldn't mount it as low as I originally wanted to.
Following is a link to some pictures if anyone is interested.

I also received my supercharger rebuild kit from Craig Conley at Paradise Wheels. They purchased the rights to the McCullough and Paxton superchargers from Paxton Automotive and sell complete Paxton units as well as parts. Craig has been very helpful and quick to respond to my questions. The rebuild kit is high quality and very complete and even has new springs for the ball drive plate which I didn't expect. I also bought a new improved impeller and a drive pulley. I started by replacing the springs in the ball drive plate. More pictures.
