getting the shaft?

They are covering their butts , if they balance it with new joints and YOUR slip yoke then you won't be coming back after you assemble it saying they screwed up .

As far as having to cut both ends ? does it neck down on both ends and neither end has enough for the amount you need removed ?

So if I replace the u-joints it will put the thing out of balance??? really???
I suppose I have had a shaft do funny things when I managed to put one of the caps a little too far in.
Yeah, both ends step down to the yokes, they cut enough to make it fit. I wanted 3 1/2 off but only manged to get like 2 7/8... that means that the slip yoke will only be 2 7/8 out of the trans. ( from but to u-joint center) if I need more I'll space the front leaf spring mounts back. My biggest issue with the whole thing is that I was quoted one price and paid a different price..I guess I didn't get totally hosed but just not the warm fuzzy I expected when I talked to the guy on the phone.
On a good note, I was able to find a slip yoke that uses the same size small u-joints from the /6/904 but has the large tube to fit the back of the 833, so no need for a problem solver joint :)
