Chevrolet six cylinder engines. This new drive system features a combined A/C and alternator upper mount and a stand alone lower power steering pump mount. Our unique cross bar mounting system provides reinforcement for both upper mounts resulting in a stronger, more compact mount. Each accessory has its own drive belt using a combination of standard balancers and stock GM pulleys. This is an extremely rigid mounting system that bolts to existing attachment points with no machining or modifications required.Contact Engineered Components, Inc. PO Box 841, Vernon, CT. 06066.
