I'm rebuilding a 1967 Holley carburetor. The throttle plates in the base plate were a little rusty in the secondary and the primary throttle shaft was a little bent so I took the base plate apart by filing off the ends of the screws. Worked great. Built a fixture for the press to straighten the shaft. Worked great. Now I need some parts.
Does anyone know of a source for the original type throttle plate screws that are flat with a slot? The screws I've found are rounder with a phillips head. These seem to be the current replacement. Also I would like to know a source for the black phosphate throttle plates or how to refinish them. I've found three base plates in my collection so I've got a pretty good selection of throttle plates but none of them have a finish as good as I'd like.
