Classic Auto Air Install Experience

I think somebody on this forum wrote up extensive information on modifications needed and potential edits to the instructions and offered it to Classic, if I remember correctly, they showed zero interest.
One day I may jump in and attempt an install, but for now I am more interested in getting my car to a reliably usable state. Once I have the bugs worked out and know I can trust the car to take a road trip or two, THEN I might pull the plug.
