I made the shiny thermostat housing also. I have those for sale.

Which brackets are you using? Truck, Caprice, or F-Body? Or Does it matter?
5.7 full size truck brackets are the ones pictured above. The 4.3 S-10 brackets will also work, but have less mounting points. The F-body brackets will not work in G body cars because those brackets move the altenator up higher IIRC.
The silver are 5.7 and the black are 4.3 S-10.
