My problem is that I have been airdropped into the middle of a minefield, and I do not want to make a wrong step. Anywhere. How would I go about installing the modern air handler into an antique dashboard? I am okay with fabricating, but I do not want to spend several hours attempting to get it to "work." Would putting spark plug wires inside of stainless steel tubing cause any problems? And is the water pump issue a valid concern? Sorry if I am getting annoying with these questions, I just want to be sure of what I am doing.
