***WANTED: Pair of 3-step (old) AFB Carter 16-405 metering rods***

3 step rods were used with the AVS with tall jets and domed rod covers and the AFB used a 2 step rod short jet and a flat cover. Just be sure use the right groups. If you can afford it buy the Edelbrock Strip Kit and use the flat top covers.

Right on the AVS, but the older AFB's used the 3-step rods, tall jets, and domed covers as well. My '67 4295S AFB has the tall stuff, and incorrect size rods, so I'm just trying to get back to stock calibration.
