I think this will be a better (and cheaper) way to clock the t-case than buying a ring. This is my Bronco's ORIGINAL ('83) NP208F, which grenaded a few months ago. I'm cutting the front off through the factory-threaded mounting bolt holes so I can put sharpened bolts in backward, and use them as center pricks to mark the transmission extension. This is the most-precise way I can think to do this, without using Ford/NP's original blueprints & CNC machinery.
