Another Xj/ Jk parts swap question.

Anyone tried to install Jk d30 outers on an XJ d30 for the bigger brakes and crossover steering yet? I'm thinking it may be as simple as just installing Jk ball joints in my d30 to swap the outers over, but figured I'd ask before I spent a bunch of money on ball joints I couldn't use. And the steering wouldn't be an issue as I've already gone over to heims and am prepared to drill the Jk knuckles IF this is a plausible swap.

Bump. C'mon guys, I already have the outers as they were free, so I don;t want to buy WJ outers if these will work, nor do I want to tear down one side of my axle to see if they fit and find out they don't.

Measure em up and compare? There aren't any JKs in my local pull a part yet, so I haven't even bothered considering or looking at such a thing.
