I have read much but know very little about how sophisticated a repair/rebuild this would be. Admit I'm a bit intimidated after reading JackFit's incredibly detailed Gary Ramadei rebuild story, so would appreciate any good thoughts or advice. With apologies for stating the obvious, I want this done right and done once.

1. How long a job (avg) is it for an experienced tech to rebuild a midyear differential?

2. What should be my expected cost?

3. Should I seek out a tech specifically experienced with midyear diffs vs someone with general diff experience? Are our diffs that unique?

4. I am not concerned with originality (that ship sailed long ago.) Is it possible to buy an already rebuilt midyear posi diff, or are there perhaps any newer, better diff designs available?

Much thanks, in advance!
