I don't think there are any trailing arms that will swap in. Steve (NoSweat83) tried to get a group buy together last year to have some made, but there wasn't enough interest...might see about kick-starting that again. Tubular, adjustable lateral links from the '97-'03 Grand Prix can be easily modified to fit our cars though:
