68 TH400 Modulator and line fittings

[SS396]

Does anybody know if this was the correct modulator (part # and finish ) fitted to the 68 Camaro TH400's. Some people say they were cad plated so I need some advice. Also were the cooler line fittings that screw into the case brass or cad plated ?

My Turbo 400 fittings are brass. There is another modulator part # 8623983 Those are black. Might be other parts numbers that replaced these two. Heres anothe pic I found of that part # you have.
