I did look at both companies
http://www.vintagewiringofmaine.com/ and
http://www.ynzyesterdaysparts.com/Both are very high quality but in the end went with vintage .I found the harness at Jim Carters
http://www.oldchevytrucks.com/both vintage and ynz sell the harness for $700.00ish. I found it at Jim Carter for $495.00 - the 10% for stove bolters here

They told me they only have a few left and won't be reordering any more because they don't sell very fast.Just thought I would share this saving $250.00 doesn't happen everyday.
