Best wiring harness for 73 Duster

I wouldn't bother restoring a 40+ year old harness. By "restoring", I mean going through all the work of pulling out and inspecting the old harness and splicing in new sections where any of the wires look bad. The problem with that is that with wires this old, they can look ok on the outside, but the inside is corroded. Then problems arise later and all the work was for naught. Also, splicing in sections creates points of potential failure/problems. You would need to sand down every blade/connector to make sure every square millimeter is making new/shiny metal contact to replicate the effectiveness of new connectors. You would also need to take apart the bulkhead connector and clean those contacts. I didn't want to go through all that trouble of restoring for a subpar/old system with as much (probably more) work than installing a new and updated aftermarket setup. I went with ron francis and happy with it. Good instructions and support. Install was easy-just took time. I completed it in about 2 weeks working on it with my schedule. You are also given a color coded diagram for the entire vehicle. Now you could use your old harness as a guide to replicate lengths/colors and gages to build your new one. I didn't have the time for that and there is no way I would pay upwards of 1k to purchase a kit that claims to be an exact replica.
