Rewiring an early A-body

I was hummin and hawin over whether or not to rewire my 67 barracuda...so glad I did! The little stuff I saw that made me want to rewire it wasn't the half of it after I got into it. I went with the Ron Francis express777 kit...They built the kit according to my scenario and I can honestly say I do not know why you would need a better kit than this. Very impressed. Their bulkhead plate wasn't sized right so I had to build my own that fit but not a big deal.
That being said I have heard good things about American Autowire but I would like to know what they offering for the extra cash you got to pay for it?
