Intake water outlet (thermostat housing) bolts, nuts.
Both the 4bbl. and Tri-Power outlets utilized a 3/8” bolt front and rear and “each” received the front bolt that was threaded at both ends.
They came this way, with or without PS.
If you got PS, then the alternator strap was secured with a bare slotted nut on that 3/8” stud.
No washer called for with this slotted nut. See #13 in illustration.
Both bolts came painted along with thermostat housing from factory.
Chris.
