Unfortunately, this change introduced a spacing issue. The Hyperglide free hub body is exactly the same height as the Uniglide body it replaced; however, the bearing surface are 3 mm shorter. Now I need to hunt for the appropriate spacer to correct this. If I put the spacer on the non-drive side then I'm also going to have to redish my wheel, but this will reduce the dish and make the wheel stronger.
More and more, I'm seeing the value of purchasing a new tandem.
