Hunt around and you'll find someone parting a later model tracker. I got hub-to-hub front and rear for $275 total (e.g. got the thirds I wanted, plus spare cv's, spare rear axels, drums, manual hubs, etc).
Parts hunting takes patience, but you'll find deals.
One $olution is to do an ARB
... Not that I could afford it, but the ARB does get you a new carrier
