No...one begins 30, the other begins 40...the rest of the part
numbers are the same, but the first two numbers aren't.

I would, however, be interested to hear where these diffs will work
on other cars.  A rear quaife diff would allow for a more V8q-like
setup on the 200q20v, for example.  Actually, I wonder if the rear
differential assembly from a V8q could be put on a 200q20v...nah,
probably not.  The other question is...would it be worth
it...probably not, is my guess...
