Thanks hcb. I spent some time yesterday looking at mounting options - what's complicating things for me is that I have Vintage Air which adds hoses to the underdash space and I also did an electric wiper motor. I am talking to a guy on the 67-72 board who did it, and he said he mounted the box under the dash with the motor at 3:00. I am thinking I could fabricate a bracket that would attach to the dash support that goes between the dash and firewall. Need to do a bit more "engineering".
