1973 340 Exhaust Manifold Heat Stove

I guess this is the correct piece. I also a pic of one on a car. Hard to believe it is thus hard to find. We are going to try to alter your piece to fit the manifold and use it until I find the correct piece.
Yes it is, but that stove is different than yours. Look at the length of the bottom tab. It is also different in several other areas. Yes, I need both correct pieces. Notice where they connect.......
