yes, YnZ make harnesses to order, don't stock them ... instructions need to consist of numbering the wires and listing where they go, along with the factory schematic [which you should have in your shop manual], and I think they all will have that [see
this thread 
] .... I think nearly all the "original style" harnesses available are about the same and factory correct, I'd go for best price from a dependable vendor .... and on a 58 you do not want cloth wrapped [YnZ's specialty, pre-55], they were originally vinyl taped
