Sorry Jake, what I meant by the 'hardware' comment was that the only item in the case that has been changed is the plug for the drain & fill points. Those plugs are hardware which is free. Otherwise there are no changes to the diff casing which is clearly stated must remain un-altered.

This is what D.4.d says: (emphasis mine)

d. Hardware items (nuts, bolts, etc.) may be replaced by similar
items performing the same fastening function(s).
So the hardware is hardly 'free'.

I can't believe people are actually trying to justify this as legal. Engine oil coolers are expressly called out as legal. Why would you think that this wouldn't need to be the case for a diff. cooler?
