67 A-body wiring harness

Need to replace the engine wiring harness on my 67 Valiant. Where is the best place to get one? Not sure yet whether I'm going to run a small block or big block. I can make either work if I need to. Thanks

Here is a good tip, the big block and slant six wiring harnesses are the same, same part number! I usually use Evans, but they are very slow.
