yeah, I was confusing ug and hg, because I had a uniglide compatible hyperglide with the thread on cog. the respacing can be tricky because of the added stress on the hub. especially with the flexible qr hub. A shop near you might align the dropouts for you (after respacing).. park makes a tool for it.
