Oh I am not doubting you or your skill level.
I am confident that you will get the job done.
Years back it sounds like something I would have tackled.
Per your request I was just pointing out a few of the bums in the road.
Put your head down and go for it.
My Barracuda has a factory A/C system otherwise I would be right there with ya redesigning the wheel.
Good luck we'll all be watching
