Well, a buddy of mine who had a Tbird (89-97) same as Cougar.
Make a long story short...the springs were from his car and he installed them himself on his tbird. Got rid of the tbird, asked if I wanted them for the Cougar. We began to install the springs, and the upper control arm ball joint would not separate, so we were like forget this, didnt want to have to replace the whole control arm. They just got replaed a few months ago. So then we stopped, because we didn't want to damage anything.
In the meantime, I havent found a place that wants to install them. One place was going to, but since they werent in a box with instructions he said no.
Well I know the fronts are coil overs, I'm not sure of the rear though.
What part of CT are you at, like whats the largest town nearest you?
For me the closest I would have to say is New Haven.
