I have a used M96 gearbox case with intermediate and output shafts (no input shaft). I think yours is an M94 but if an M97 will work then so will the M96 I have. The bearings in the M96 were tapered, not sealed, but the case is the same. The taper bearing has an outer race diameter that matched that of the sealed bearing in later models. I'll make you a great deal on the case. PM me if interested.
EDIT: As others have mentioned, the tech made a HUGE mistake and it is all his fault. Those bolts are known to be very difficult to remove due to the red loctite used from the factory, large steel bolt torqued pretty tight and a soft aluminum case. Heat and patience required.
