Driveshaft length for a Viper tr6060 and 8.75 rear

Not sure if your Viper TR6060 has the same overall length as the aftermarket T56 Magnum...

In my Duster with a 340, factory 73+ spool mounts, T56 magnum transmission and a ToddRonn crossmember my driveshaft ended up being 45 3/8" back to my 8 3/4 with 1350 joints.
