Wiring Harness

I have a 72 dart swinger that I am in need of a new wiring harness for. I order one from Year One back in the beginning of June and here we are in the middle of September and I still haven't received it. I have called and all they tell me is they are behind in getting them from the manufacture. If you look at their site they still don't have it listed as out of stock. I am going to cancel my order with them and order else where if possible. Anyone have a good suggestion of where to go to get a new wiring harness? I checked Classic Industries but they are sold out as well.

Any suggestions would be helpful.
