At the wise and mature age of perhaps 20, I replaced the front springs on my 70 Esprit W/AC. The original springs were really shot and bottomed out going over a #2 pencil on the road. Armed with my engineering curriculum, I used a come-a-long winch anchored to the opposite leaf spring perch to pull the LCA all the way down. Wedging the flat tip of a crow bar under the bottom coil popped the spring out without too much effort or recoil for that matter.
Using that method in reverse was a whole different story with the new springs, special service part numbers recommended by my automotive prof, Jim Lyons, later head of the Pontiac turbo development. I had to go to the GM Parts Warehouse in Schwartz Creek, MI to pick them up in person.
I did cable them in to the spring tower so they couldn't fly out and punch a hole in the garage wall. But I must have beat on each one with a sledge hammer for 10 minutes to slide the bottom coil back along the crow bar and get it into the pocket. I later heard a local spring shop would have compressed them and steel banded them for $25, but heck, I saved $25.
Professor Lyons was right though, those springs still hold the front end up well after 120,000 miles.
