by low profile do you mean integrated?

With the top race and bottom race installed, I would get about an inch of threaded steerer, which is not going to work with a threadless stem to my knowledge. Though, aren't some of the true 1" stems shorter than their 1 1/8" counterparts? How much weaker is threaded tubing? The headset has been disassembled, but I haven't removed the cups yet. Thanks for the socket idea. The races were all pitted.

Like I said, I want to use this threadless headset and I don't mind getting a new fork even if I have to wait. Just getting excited about getting it to work and was wondering if their was an option for using my current fork. There isn't. So i'll wait. It's a learning process. I will pop out the cups tonight to see how the new ones fit.

Another option I have is disassembling my other bike's headset which needs to be rebuilt anyways. it is threaded.
