OK, How will the final drive enter into this?

FF     3.89	 3.45	 1.94	 1.29	 0.97	 0.76
4K     3.94	 3.45	 2.12	 1.44	 1.13	 0.89

But isn't a 5th gear swap a lot easier? You will need an end cap and 
might want a gasket for the gear cover.

I too recommend if you _do_ swap the whole unit after a clean out you 
stick the 4k and some tools in the hatch so you have a way to get home.
