The sm465 to nv4500 swap does have a few unique challenges. The shift tower is about three inches rearward on the nv4500. This is beginning to intrude on the transfer case shift lever, but it can usually still be made to work. The passenger side slave is the worst problem with the 92-95 nv4500, when installed in a 4wd truck. For a 4wd, you really should go with an aftermarket bell, or a 96-07 nv4500 and bell.
But otherwise, the length is the same, the spline counts are the same, the slaves displace about the same amount of fluid, and the external dimensions are basically the same.
