Buddy Bar casting is still in operation today. http://www.buddybarcasting.com/Home.html
They produced the cast aluminum intake manifolds for Ford back in the day.
The original Boss 351 intake was an D1ZX-9425-CA. It was an aluminum dual-plane intake that took a spread-bore carb. ALL Boss 351s came with the "CA" intake. The intake you have D1ZX-9425-DA was an over-the-counter intake that is identical to the Boss 351 intake except it takes a square-bore carb.
