Here is a pair of Spax Eliminator adjustable coil overs. They are about ten years old and the shock part number is 4-54685. Extended length is 13" and the eyes are 3/4" but of course could be bushed to 5/8 or 1/2" No idea the spring tension but they didn't move much in a 2200# A coupe. These were replaced during a complete revamp of rear suspension. I can ship them if desired but please take a guess on the shipping to decide if you want them. I'll figure it out once I know you want them, they are dirt cheap. Getting a little tired of calculating shipping for someone who never replies much less says thank you.
