Skreddy
SILVER Star
I am looking for some answers on specifically this unit; not who’s is better, references to a unit no longer produced, a different style, etc.
So, Old Air 400HCD is a under dash version, similar to the Vintage Air slimline series. I’m looking at this because I’m debating on AC in my 1970 FJ40 and I don’t like the look of the newest version VA kit with the 5 round louvers. The VA Slimline is about 2” taller than the OA unit. The OA has floor heat that comes on when the defrost is selected, the VA doesn’t have floor heat but can T off the defrost hose and add floor ducts. Those are the 3 reasons I’m considering the OA 400.
The questions I have about this specific unit are;
How’d it fit?
How well does it work?
How does it work? They said there’s 2 knobs and a pull cable but the pic is poor at showing this.
They don’t offer a mock-up case for this unit to see fit or how it operates before buying the whole kit.
