Professionally rebuilt by carburetor exchange in El Monte, California in august of last year (2019) and never installed. I got it rebuilt, then when rebuilding the engine decided to go with 2x2bbl progressives. Ran this exact carb for years with no issues, and the company that rebuilt it runs them on a test engine after rebuilding. So should work great! Not sure exactly what it’s from, but I think it’s from an early 60’s truck. Price is the cost of rebuild + shipping. Will trade for a 53-54 sedan delivery Gas fill neck. Text Greg at (626) 672-8110
