My other thoughts are maybe this bushing is either a mis-box, or Chinese junk. I don't totally remember the brand, but I thought it was ATP. Anyway, I do have another one of those inbound.
I would cal A&A in Indiana and ask them if theyve ever seen the issue, then buy a bushing from them to be sure it works. Maybe they ( or anyone here ) can provide you with an od measurement commonly found on the OEM yokes??
We may find that you need the driveshaft balance checked again.
