Looking for a 7.4 Intake manifold. It's a 1989 340EC IB. If anyone has any suggestions on a good place for good price, let me know.
 
The boss for one of the bolts to hold on the thermostat housing actually broke off. It appears the previous owner had a leak at the housing and over time the water puddled and rusted it enough that when I tried to remove it the whole boss broke off.
