Driveshaft length ??

I would post it publiclly that he sold you the wrong part & will not make good on it. The other members should know who the stand up guys are & who aren't & I'm sure he will see the error of his ways & make good on it once people start responding. I think the 1 you need is 54.5 or 52.5 long is I remember right
Nope, the driveshaft should be around 49" long, center to center of the u-joint. I think you both were a little negligent in not doing some measuring before the thing was shipped. Not knowing what was stated in the e-mails, we have no way of knowing who said what. What do the two driveshafts measure?
