I've heard the TT IIs have trouble fitting the bigger calipers.
Seems like a lot of people are having trouble getting feedback from Ed lately. He does the brake kits on the side of his normal job; so, I'm sure he can get backed up and busy sometimes. It took him longer than expected to get mine done, but I wasnt in a super rush. If you're not in a big hurry to get the brakes done, I'd wait on Ed to reply; he builds and mocks up each kit individually so that he knows everything fits before it's sent out.
If you are in a big hurry, there are people who sell just the brackets. I know you can do a search on montecarloss.com and find them.
