The front carb has the correct top without the choke setup 6-1299 and Bowl 0-1953. The rear carb top is 6-1271 and Bowl 0-1518. A NOS AC Filter as well as the steel gas lines and fittings are included. Carbs will need a rebuild kit. Good for a performance motor or a starter setup for an Original DQ Setup.
