Thanks,E, I appreciate the comments on adding Dynamat or Fatmat on the firewall AND under the cowl, that makes good sense. Am looking at the Hot Rod Air system for the A/C, as they will be able to use my existing controls to work the A/C, while replacing the huge heater box, fan, etc, with a more streamlined unit. I can't use the original A/C systems because they can't handle heat around 110 to 115 degrees! Six Shooter, I don't plan on a lot of driving while I wait for my dash to be returned, just to get additional work done. The 260z dash you mention is probably not worth the cost of shipping and it may not fit anyway. I appreciate the thought!
