This is news to me. I looked into Hotwire and was led to believe they did not have the NAG1 stuff figured out, maybe that all happened after my debacle. Awesome news it is though as this drive line with an 83/4 rear is great! I have a 2.76 gear and I get 20 mpg 70mph=2000 +or- rpm. It is pretty quick off the line and I can smoke the tires all I want .It chirps 2nd and 3rd when I am on it hard but not spinning the tires. It would be a beast out the hole with even a 3.55.
More guys will make this swap now the right equipment is available. It is worth it!
