why are my CVD's to short ??

[mmdooley]

Thanks for the help guy's, Maxxdude: my drivecups are the 7.5 1/8 gears so I can't use the old drivecups. Gustav: I am worried about the play in the cvd's. They were like that when I got the truck. Does anyone else have that much play in there cvd's?? Can anyone tell me how long a RDlogics cvd is and how long a MIP or UE is?? Measure the whole thing like I did in the picture at the top of this thread.
