I had the usual problem with a stuck diff plug and, later, the same on a transmission plug. I ordered the correct square 13mm socket from the site below and, with a breaker bar, found it to be very easy to get the plug out.

The site says it's for R160 and R180 diffs, but it fit my R200 perfectly.

I'm now going to get one of these for that stubborn trans fill plug, which is showing signs of getting rounded...

These aren't cheap, but it's nice to have something fit perfectly (vs. a 1/2" ratchet or bar) and not round the plug.

FYI: It's not my site and I don't know the owner! :-)

Didn't we already cover that in the other thread a week or two ago?

Hmmm...I searched and didn't find it, so thought I'd post.

I didn't catch any other thread, so I appreciate the link

We talked about that here:

Wow...I posted to that thread, too! Obviously, I've been inhaling too much of something in the garage...
