Greetings, all:

I have been trying to replace the rear lower control arms on the 86GT and so far I have a used set of arms with what appear to be decent original bushings on both ends. I know the factory bushings for this part are difficult to locate. Don't want poly so don't suggest it. Question is, how can I compare them without actually installing them? I plan to replace the upper arm bushings at the same time. The arms on the car are the original ones with the of course original bushings and while the ride isn't bad, it is getting rougher. I did manage to replace the spring isolators about two years ago which improved things slightly. All front bushings are new rubber and really helped the front end. Now I need the back to be better. Ideas? Thanks much.
