Peter Campbell, I looked at the NVG page , not much info. I noticed that the model 271 was way serious when the Super duty's started using it in 1999. I would like to up-grade to a 271 but I would like to use a bolt on rear yoke. The Ford version is a bolt on but I would have to change out the input gear to the 1-1/2" 29 spline to work w/ my 5600. I have checked w/a tech at NVG and he stated that the Ford version has the same bolt pattern as what we are using and that I could change the female input gear to join a Ford case to the NVG 5600. I am hoping that the 2003 Dodge case offers a bolt on yoke to help out on the modifacations to an already EXSPENSIVE transfer case.
Thanks for the info and if You have any suggestions I am all ears.
Thomas
