This project is on the horizon and it's time for me to start getting smarter.
History: We purchased this car back in about 1998 and it had a Vintage Air A/C unit in it. It would never hold a charge and the case leaked condensation on the floor. This car was never a factory A/C car and I have decided to return to just a factory heater. I know, I live in the Mojave Desert and this sounds certifiably crazy, but that's what I am doing.
This also plays into another goal with this car which is to make it fool proof. Less things to ever go bad or wrong. A basic principle of the project is *Simplicity*.
OK, enough of that.
Everything from the old Vintage Air unit is gone. All I have is a big hole in the firewall (covered with a makeshift plate) and the dash controls and cables for a heater.
I will soon be pulling the front fenders off the car and of course the engine compartment portion of this heater has to be installed while the P/S fender is off (blower assembly).
I also will be surprised if I don't have to do some sheet metal work around this hole, I don't know how much more of it is cut out beyond the factory opening.
I'll be hoping for advice from anyone that has done this *from scratch* installation before.
First question is: Does it make sense to just do the engine compartment portion? ... leaving the under dash installation for later when I rewire the dash? This would just be a cash flow management decision. Or would it be a much wiser choice to just do the entire install at once?
Past experience does tell me doing it all at once would have some advantages, namely the ability to be more certain something on the outside doesn't get installed slightly out of position making the interior install more difficult. Keeping in mind that the hole in the firewall is quite likely not perfect right now.
Any advice before I start? Are there any small parts of aspects of this install that might be easily forgotten of missed making things difficult later? Are the aftermarket parts for this of good quality and fit?
I have a parts list done. It's about $800.00 in parts. (Classic Industries)
