These parts are now anodized.
 
The aftermarket thermostat housing makes radiator hose routing much easier. The outlet for the thermostat is straight towards the passenger side. The outlet is tapped to 1" NPT. There are many adapters available on Summit Racing to give you whichever hose size you require. https://www.summitracing.com/parts/mez-wp1175s
 
You can now add my custom-made 1-3/8" Barb adapter, made specially for me by Meziere Enterprises. This is the same as Meziere's 1-1/4" and 1-1/2" fittings, but fits the common Toyota, Jeep, and GM (LS) radiator hoses. These are all clear anodized.
