Yeah I was saying above I need to pull the hvac box anyway to get floor duct out of the way of tunnel work. And hvac box needs a rebuild cause I was planning to put AC in before next summer. And AC been unhooked since 1981 and main hvac never been out of the 54 year old car so its all crudded up for sure. Once hvac box out I can cut floor heat duct off and fab a new one that sits 3/4" to 1" higher for the raised tunnel. You'all been telling me make tunnel roomy and now that trans is up in there yeah I want the tunnel to be nice and roomy not tight.
