wiring and mirrows1941 cad 60 special

[mr41cadillac]

my wire is great but the outer covering is flaking off.  does anyone make  an  outer covering that looks like original. I thought I could cut the connector and slip on the new covering and not have to remove the entire wires from the car. the wires were wrapped in places with what looks like cloth as they branched off. also I bought 2 outside mirrows but they are not wide enough to clamp on door. who makes  outside mirrows that will fit the 41 60 special. thanks john
