My guess on the reason they do not make these wires exactly as originals is they are using left over tooling from someone. 15 years ago you could walk into a NAPA dealer and get a set of Beldens for a mopar and guess what-they were black 7mm with the same color and shaped boots as original, minus the makings. I dont know of course if this is the case, but possible. It would not be that costly for them to make the molds for the boots-they are very simple molds, I have a friend who builds these tools everyday-he could have them built in a day.
