Well I measured the Dazon shaft today, and it is a hair over 3/4, so the 3/4 unit will work for that.
As for the Yerf, I was thinking of sleeving a portion of the upper shaft to get it to the thickness needed. Also thinking of adding an actual bearing or bushing at the top most column mount for added support. If I do the Yerf, I may also look at shortening the shaft and column while I am there, and making the column straight, instead of offset.
If said sleeve was made long enough to to go in the bearing and also the QR hub, I don't see that failing unless I start juicing, and I can't afford that.
