I emailed Dan about this and heres what he had to say:
"I have had a couple customer install the dogbone kit and thought the front dogbone was too long. When i probed a little further, I found out that the cups were installed with the stock set screws with pins instead of the supplied 4mm set screws. Makes all the difference."
