I bought the RX-7 I posted here: http://grassrootsmotorsports.com/forum/grm/what-do-yall-think-about-this-turbo-swa...
I've already begun tearing into it to remove the audio equipment and rat's nest of amplifier wiring. I found the battery was relocated to the storage bin behind the passenger seat, however, it is not tied down. I found this tie-down on Amazon and was wondering if it would be acceptable for SCCA Solo and track-day organizations (i.e. COM Sports Car Club). It says it is NHRA-compliant:

Also, in the other thread, Brett_Murphy mentioned something about battery gases escaping through a rubber tube. Would this be necessary with a sealed battery like an Optima or Odyssey? What would be a good way to route the tube if it is needed? I was thinking of keeping the tie-down in the storage bin where it is right now.
