[C320-list] Starting Battery Installation

[jonvez at comcast.net]

Quentin,

A G27 fits fine in front of the 4D's. I coated a piece of plywood with epoxy resin and then glassed it in. Jeff Hare has a great schematic for this project on the web site. Take a look if you haven't already....

Regards,

Jon Vez
