My suspension setup was pretty close to M_Bodiy's setup when I first put my Mirada back on the road. It drove okay for an old car. I put the 300# Firm Feel bars in and the ride was far more modern feeling. My Mirada feels far better controlled while driving, and handles better.
If I had to...
I must have used a shop press to get my front bushings out. I don't even remember removing them..... The rear mount has an over travel stop for the shackles, I think they called them tensioners because Chrysler liked to use there own terms
