Our kits include all the required parts, including the rear pump rod. These are all the parts you need to convert from Vacuum to mechanical linkage. Includes slide bar, J shaped bracket to attach to center carb,slide bar to rear carb, rear linkage arm for rear carb, rear carb pump rod, all bolts, and parts needed. Includes new set of torsion springs for end carbs. Specify GTO or full sized Pontiac when you add item to cart. There is a difference in the kits. Picture is of linkage for GTO. Note it has a post where the cable would attach on a GTO. Full sized cars would use a ball stud in place of cable stud. Kit does not include the long rod on passenger side that runs from rear carb to front carb. This is the same part for a vacuum linkage car, so many already have this piece. If needed, it is also in the shopping cart.
