Paul. the trailing arms are all the same .only difference is between disk and drum..(mounts for disks)  Thats a cheap fix if you dont replace the trailing arm
Step 1  burn out remaining rubber bushing leaving the outer ring still in arm
Step 2  relace bushing with a energy suspention eurethene bushing   35$  and about an hours work
Hope this helps

Thanks Curt, I have replaced them on the GSR so I know the process isn't that difficult but we are preparing a car for LeMons and we don't want to show up with brand new red poly bushings and have to explain how a car that's supposed to be worth only $500 has such a upgraded suspension system. I was hoping to just pick up a set of trailing arm that fit that looks like the bushings are in better shape than the ones in the old ice racer/new LeMons car
