Rear Diff

I'm fairly certain I've mentioned this, but I definitely need to find a limited slip differential for the project. The most obvious choice is from a 70's or 80's XJS with a V12 because they're the exact same as what's in mine, only with different innards. The problem is that I have been having a lot of trouble locating one in the states.

Which is when I came across a listing on UK ebaY motors. (On a side note, I really don't understand why ebay is always written with a capital B... on the Web site it the letters are lower case except for the Y. Oh well, whatever.)

So I realized that there are a ton of listings for Jaguar rear diffs on the UK ebay motors site. One in particular, right here, is the EXACT one that I need. Should I spring now for it? It would probably cost upwards of 400 USD. Or should I hope that it's a usual occurrence for these to show up/hope that I can find one in a junk yard somewhere.

I'll probably choose the latter due to lack of real funds for it and not really having any need in finding one right away, but I will certainly keep an eye on it.

One more thing, just looking at pictures like this keeps my curiosity and excitement going for hours.

Yeah, that probably sounds really weird and lame. Oh well.
