I need a new differential (not axle housing) for a W-350. In my research so far I have not found any aftermarket options. The "Bill of Materials" (605512-8) on the axel housing says it is a Dana 70-2U, 3.54, Limited Slip, 32 spline.
Are there any aftermarket differentials for this housing?
Is there any chance of finding an internal parts kit for the original case, new old stock?
Unless I can find some different options the list below is what I understand I need to purchase.

- Differential case assembly - not available
- Empty case kit - 708019
- Inner parts kit - 2021290
- Ring and pinion kit - 708015-1
- Case bearings - 706047x
- ABS tone ring - 42929
Fluid:
