I've just replace the output seal and bushing on my NP208 - again. The bushing was actually fine. The slip yoke mic's 1.875" and is in new condition. I have a few more yokes and all appear to have radial play on the output shaft so it appears that the tolerance between the bushing and external yoke surface is too large. I've validated this before the install by examining free play between the bushing and yoke. Q: Anyone out there found a speedi-sleeve for a standard 1.875" GM yoke? I'd need one about 4-5" long I think.
