Can't get much simpler than rebuilding the np205... I rebuilt mine with never having rebuilt one before and had no issues. I believe that box on the end of your speedo cable is an aftermarket piece to compensate for running different size tires than stock. I didn't have one on my tcase. There doesn't look like there is anything that needs rebuilt on it. The sleeve that threads into the tcase seals the fluid from getting to the cable so I imagine you'd just have to grease the gears in that box up anf bolt it back together.. Or if you're going to run a stock size tires you can just leave it out all together.
