Hi Mark. When they were first fitted I had some assistance from a very strong garage mechanic who compressed them on the car. This is not the way to do it, and he reckoned he hurt his shoulder in doing so. When I later removed them to play with the ride height, to no avail, I wired them up as described. I have to say I did wire them up on the car, so they were already compressed. However I'm sure you will be able to compress them using the vice method. My cast steel swinging arm has a single upright bracket which the eyed end of the shocker simply bolts to, so I can't quite understand clan man why you couldn't fit yours. My car is an 83 GTL, a late car like yours, so both should be the same. Anyway Mark, keep us posted please.
