Default Thermostat housing / water outlet

Hi all!
So I’ve tried everything to get this housing. Tried all the parts stores, even ordered the “77-81 trans-am 4.9L” housing.
Anyone here have a good part number?
This $20 part is the hold up.

Every one I got the bolt pattern was to wide.

Thanks for the help!!

The Pontiac housing fits 351's with the thermostat on the front of the water crossover. A 1965 should have a crossover with the thermostat on top. Does your truck use a thermostat housing with a vertical outlet or a horizontal outlet?

Small block Chevy does not fit it is to large. Bolt pattern is off by about 1/4” on each. And the gasket is to large to hold the t-stat in place.

I had the same problem with my thermostat housing. I had repaired it with Devcon 10760 Gray Titanium Putty, 1 lb. Can. Be sure to bead blast the housing before using it. It is the most chemical and temperature resistance version they make.

I just realized the price of that stuff really went up.

I included a before and after pictures of my housing.

I found this one for an older Pontiac, but the outlet is more vertical:
