Trace, here's what I was told when I inquired about retrofitting:
Unfortunately there is no retrofitting the old and new designs. Specific fabrication to the glass and 1 aluminum component must be done in the manufacturing process.
While I'm not sure if they have a customer service department at this location, I did find this phone number: 800-536-7324 (SEA - Ontario, California).
