tiger firewall

[Barsness Jeff <barsnej@wsdot.wa.gov>]

Hi there, I just recently aquired a pair of Alpines. One is a complete
rustbucket and the other has a solid body but only about 50% there. I'm
planning on Tigerizing the good Alpine. What I would like to know is the
diminsions on the recessed area in the firewall to clear the motor. My
plan is not to build a Tiger, only a hot rod. Any additional advice
would also be appreciated. Thanks alot. Jeff Barsness
