If you are less concerned about originality, I used a kit from
Rebel Wire in a 1950 Ford sedan and found it to be a very good product. Napa still sells the old-style woven wire loom and fabric tape; if you are careful, you can hide about 95% of the modern wire that way. It is easy to use and install, but it isn't a factory replacement by any means. I was happy enough with it to purchase another one for my pickup.
