I can only speak for the MAC valves....Tom and I redid the ones in back.....it's just plumbing, and hooking up the wires. Tom took a picture of the original cluster before we took it out, and then blew it up and printed it so we could use that as the "map" for rebuilding the new cluster.....we used the picture extensively for both the plumbing and wiring.
