I bought the 21 circuit EZ Wire for my '33 and had no regrets. Conductors are well insulated and flexible, and circuit name embossing is clear. I had reason to call them to clarify how one circuit needed to be run, and their tech guy was patient and helpful. My only complaint is that I mounted my fuse box too high with the dash out, and now with the dash in place and AC/defrost duct tubes blocking the view getting to the box to change a fuse is a royal pain.
