Just did a Google search under "falcon floor pans" and got some interesting hits.
Rock Auto, which advertisses on this board, lists pans for $50 (must be four panels at $50 each as the half panels used to cost way more).
Also got a link to another Falcon site:
fordfalcon2000.com
The New Millennium.... Falcon!.
Okay, so it is a rivial to this board but there is a COMPLATE photo coverage of replacing a 64 floor with one from a southern car forund in a junkyard. Looking through that sites links I found COMPLETE coverage of installing the T-5. Now I know where the new T-5 from my 85 Mustang is going when the Mustang is junked next year.
