Brom used to (and may still) sell "roll centre correctors" to fit to 2wd or 4x4 hubs to replicate the 3dr hubs - they are 1 inch approx spacers that fit between the TCA and the hub carrier. May be of use to you if you can't find any 3dr hubs.

I bought a set of 3dr hubs off Tim via ebay for about £52 a couple of months ago, to give you an indication of price (and make you jealous). I haven't fitted them yet, and I've got a spare 2wd hub knocking aroud, so I'll try to take a photo tomorrow, and a photo of the "roll centre correctors" that I've also got knocking around.
