If it's a Mopar part try Paul Kwiatkowski at Peter Stockill Ltd in the UK. His direct phone is +44 1482 330468, or email
chris@stockill.com (they haven't changed email addresses since he took over as Parts Manager). He supplied my clutch for A$235 (plus A$220 air freight!) and it arrived within 2 weeks: this compared with Jeep Australia wanting A$730 and saying they could get it in 4 weeks.
