The battery is mounted to the swingarm under a louvered chrome HD battery cover. Here are some pics of the build:
Rescuing the donor.
Tearing off all the stuff.

Another 100 tries at cleaning up the guts.
Nearly done. A little more sorting to do.
Okay here's one more: The nearly finished GZ with my not-so-finished Lambretta SX200.
