Default Thermostat Housing question
'73 L48:

My current thermostat housing is cast iron. I just saw an ad for an original thermostat housing that is cast aluminum. They look the same except for material.

I believe the correct part number is 3877660

Does anyone know the correct metal for a '73 L48 thermostat housing?

thanks

the 3877660 housing is aluminum and should have the part number on the neck
