    My thermostat housing has some pit damage but the flange looks ok, so rebuilding mine would be a waste. That will be cool to see how those aftermarket ones look after you make them work for the SC. Keep up the good work!

    My housing came in and it looks in good shape. Please PM me the address. I assume the housing rebuild includes a new flange?

    Yes. New flange welded on, new gasket and refinished.

    I was able to spend a few minutes this past weekend finishing the CAD model for a prototype adapter that will work with the generic aftermarket thermostat housings and then cut it out on the mill yesterday. I still have some development and machine work to do for the the fittings and bleeder but the housing itself is essentially done. That stuff will wait until the next time I order fittings/metal. It is essentially a 6061 aluminum sandwich with a gasket on both sides that would go between the intake manifold and the generic housing. It is currently a bit thicker than it probably needs to be at 1" thick but I can probably cut it down to around 0.700-0.750" or maybe even a bit less. The sealing surfaces were not machined yet as I am still working on them. A curious thing about the generic 3.8 SC housing that I bought from Rock Auto is that the flange on it is the same as the SC flange but mounted upside down on it. It is almost as if the engineer that copied it accidentally mirrored it in CAD before they had the tooling made for it and they got stuck with having to use them.
