huebler shaft
Contact Ryan Theewen of Rat Cues. He works out of Muellers. I read on here once that he has a bunch of Huebler rings that he purchased after huebler closed his doors.
You are better off having him make a matching shaft with a taper to your liking.
I saw his cues at SBE last year and they were really nice....as he was a pretty cool cat as well.
If you look at the cue review section, there are a few reviews on his cues as well. People have commented that they were really nice cues with a great hit.
Hope this helps
