A lot of the euro 500s had 224 diffs.

Nope it has 2.47 stamped on the housing and on the internal gear as well....the 617 would probably just climb out of the engine compartment and crawl away in protest if a 2.24 was used.

I may be doing the same project on my car sometime in the near future, I will try to do pictures for that one.

The bushings are easy, you just need a flat blade screwdriver to work it in. The hardest part is getting the retaining clips on/off without it twanging off into oblivion.

If gear oil isn't for axles, why do they all have oil in them? I put in what came out....which was gear oil.

I only let my little electric impact hit it like 2-3 times.....its no air tool. It can't be much more than that in torque spec because removing it only took about 3-4 hits from the impact....it came off quite easily. I'm not too worried, it is quite durable looking and seems to be working fine....
