I am wiring my 1951 Chevy 3/4 ton and need to know if anyone sells some kind of device that covers the wires coming out of the 1" hole in the firewall. I am keeping my firewall clean but all these wires are looking like a bunch of spaghetti. I will be using the split loom but I would like something up there that covers the wire coming out of the hole so that it doesn't look so obvious.
