I would only suggest purchasing these throttlebodies if your originals are un-restorable. Bases are fitted with new shafts, throttle blades and have the levers attached on both the passanger and drivers side. Also have the small center 59-65 and the large 66 center throttlebodies on the page. Comes with the neccessary gaskets. If you have your orginal bases it is best to stay with those, we find that most customers do not need new throttlebodies on the ends. We charge $130.00 a pair (both end throttlebodies) to restore. This service includes pulling yours apart, inspecting shaft for wear, glass beading all parts, paint throttlebody, re-assemble, seal blades, install new torison springs. If your passenger side levers are not damaged, will replace them with replated orginals. Price includes shipping back if you are in USA. E-mail for details. Usually a quick turn-around ....just a few days.
