I just picked up a 4.27 geared 72-75ish narrow track Dana 30 for the front of my old Willys. Does anyone know the measurements for the factory 6-bolt spindle mounting pattern? I am going to make some disc brake mounts and this would save me some time. Does anyone know the taper of the stock D30 tie-rod ends? I need to pick up a reamer to flip the the linkage and make some bushings. Thank you for your help.
