That's good news. I just pulled the stub axles out of the old 3:54 case and lo and behold - tapered roller bearings! Everything looks in beautiful condition - even the o-rings look good, but it was definitely leaking.

By contrast, the internals of the newer 3:31 diff were dirty with a muddy, gritty sludge in the bottom. I definitely feel safer with the older diff so either I swap the internals into the newer case and button it up with all of the new brakes, etc. that I had ordered; or I just order a new set of seals, calipers and brake discs for the series 1. That's the easier option, but the relative weight of the brake components almost triples the price by the time I pay all of the duties and taxes. Return shipping cost is ridiculous, so exchange is not an option. Not a back breaking expense, but the wastage really bugs me.
