[urq] 4.11 rear diff

[n-engelbert at terrans.net]

Which 4kq rear diffs are the ones to use on a UrQ when swapping in a
200q20v transmission?  I've read on Martin's site that the 84 is the one to
use, and other places that up to early 85's will work.  I've heard
something about a single piece housing versus a multiple piece housing.
Also something about CV drive flanges being different sizes.

Will all 4kq rear differentials work, or only the 84?  If only the 84, why
not the others?

Thanks!
