Shown here is our exact reproduction of the factory big block throttle return spring bracket used from 1967 until 1969. It will work on all engines, but is factory correct for those years. These include the small tab that fits into the bolt hole in the head. These make a great general purpose throttle return bracket which looks 100% factory, but will work with most dual plane intakes. A nice piece at a price which blows the "restoration shops" out of the water.
