Kickdown linkage, small block, four barrel.

I don't mean to hurt your sale, but if that came off of a 72 Duster 340, it wasn't the right linkage. That 1 piece rod system only works on E Bodies, 71 up B Bodies, and C bodies. These bodies I have listed have about 3-4 inches from the back of the engine to the firewall. With the 1 piece system like you have shown, that is what you need. All A Bodies and B Bodies up to 1971 but not including 1971, use the 3 piece bellcrank system. Only have maximum of 2 inches behind the engine. That does look like a 72 340 E Body, possibly.
