Got my shaft back, Its only got the typical "im going 110mph in a 1971 model mopar" vibration now, but is smooth as silk at 60 through 80 on my speedo which is not accurate I have found out via state patrol.
The guys at Fast shafts were good to me, and said "sorry for the F up" and have a nice day. It still had anout .010 of run out in it, but That coud be a number of things with an old 833.
