1973 472 thermostatic choke

[Boogeyman Con Carne]

I need the one that bolts to the MANIFOLD not the carb. It's a bi-metal spring with a loop in the end to hold the primary upper butterfly closed until the manifold heats up enough the let the spring relax and the choke pulloff diaphragm open it up. If you have the rod, all the better, but I can make one if I have the choke...
