my opion would be to just swap out everything, the whole gsr/ teg suspension. the control arms and everything. fix the rubber bushings, since there most likely cracked and broken.
so do the rear disk and front disk. a whole gsr suspension should cost u about 350, then about a couple of hours of install and ur done.
i put 98 ex rear disk on my ef. ( i think they were 98 ex, not sure)
