Using early manifolds lower ac bracket is a problem. This truck has those on it when I bought it. They can be made to work but requires modifications. Using an early 6 bolt manifold on the right side requires an adapter plate for the 7-bolt head. Mine always leaked, poor design. You will also need the TVS parts, AP brackets, pullies and correct vacuum routing. Pictures attached are my 85. Hard to show much with all the ancillary equipment. Finding parts that all work together may be difficult. Get any parts available use what you can. Took a couple years to locate the AP system for this truck. good luck

What Brian is explaining to you, is the 1985 exhaust manifolds are slightly different then 1973 manifolds Mike has shown you. Does your husband's truck still have the original 1985 exhaust manifolds with the AIR pump tube fittings? Hard to see in your photo.
