1969 Mach 1, 351w, San Jose. Looking to replace the wire loom in the trunk and three self-wrapping looms are offered. Black Coated Fabric, Tightly Woven, and Loose Woven. I am think 1/4" for the section that goes over the wheel well on the drivers side since there are 4 wires and 3/8" along the trunk to the other side since there are 7 wires. Can anyone comment on the type of loom that would best replicate what was used originally? Thanks
