Manifold - Throttle Bodies

    This is like our GB 590 for the 48 IDA Webers or Berg IDA carbs with a longer top area to house the throttle plate. Made as right and left. Fuel injectors bolt into the lower outside of the manifold the same as the stock VW using the furnished hold down bracket, directing injection charge at the center of the valve. Extra heavy wall to allow maximum porting work. Velocity stacks fit into a machined recess and are secured with 2 bolts.
    Shaft size and flat are made to fit all Weber carb arms. A separate throttle stop is provided along with linkage arms that can be converted to center pull linkage by swapping the arm from one throttle body to the other. SW 20#
