Chassis heat valves

[TPorsche930]

I recently completed the rebuild of the heat valves for my '68 and have run into a problem. I purchased the O.E.M. type aluminum duct to connect the heat valves to the heat exchangers. When I went to install the hose I find that the I.D. of the hose is the same as the I.D. of the duct on the valves. There is no way the hose will attach to the duct. I've tried stretching, flattening, etc and all I have managed to accomplish is tearing the aluminum hose. In trying to find the problem I have come across many different configurations shown on different sites of the overall assy. The photo shown with the valves sold by our host show an angle on the inlet side of the valve pointing towards the engine. I have never seen this valve anywhere in a parts selling forum. Another diagram shows a cone shaped adapter of some sort as part of the assy. I've looked online for any photos of the assy. actually installed on a car, but everything I've found shows some aftermarket type hose and not the aluminum hose. There aren't many pictures anywhere showing these valves. I have also seen the hoses connected to a steel sleeve that fits in the hose and then inside the duct on the valve. That would work in my situation since both the hose and the valve have the same I.D. Any help or photo's would be appreciated.
Also, does anyone know it the original paint on the valves from the factory is actually Glyptal. Many years ago I used the red Glyptal on the inside of my race motors after deburring all the castings. I remember the red Glyptal being very much the same color as the original paint on the valves. It would make sense that the factory used this since it's somewhat a heat resistant paint. Just asking for future reference.

I think my valves look like this, but I have not studied them closely. I will look at them, but there was not an elbow, only one hose with clamps. The one thing that I find very interesting is the flapper valve in the part pic above appears to be able to be removed. Mine does not have a nut on the end and I need to remove mine. My flapper is all flapped out. The PO butcher the valve body so I need to work on it. Did you remove the flapper in yours? What paint did you use?

Not sure, but that first exploded diagram might hint at a reducer piece being available. Does the hose fit onto the heat exchanger?
