The Angle is Ok, Min. is 1*, Max. is about 5*.
I would think TCI would use a new Output Shaft bushing and your new Driveshaft should be balanced correctly.

according to them 3/4" is Min. & more than 1" isn't needed. I wouldn't think the extra 1/4" would be causing the wiggle/play but I could be wrong. You could slide it in more & see if it tightens up the play, if not the Bushing may be worn. If it's easily moved & the wiggle/play easily felt somethings worn.
I'm not sure what the clearance/tolerance is for the Yoke to Bushing.
I have one of these>> http://cgi.ebay.com/ebaymotors/Auto-...item1e61d70446
it removes & installs the Bushing without removing the Tailhousing. Real handy for 2004R Trans, as it doesn't have a removable Tailhousing.
