I have a Mark I that has a 1992 GT engine and transmission and a 1999 GT rear end. I noticed last weekend that the drivers side rear seems collapsed and the shock and wheel well both measure about 1” lower than the passenger side. This is definitely a change within the last 3 weeks. As for why this condition has recently manifested, all I can say is that Wisconsin winters are not kind to our roads and this year they seem even worse than in years past. I’ve put on just over 5000 miles in the last 3 years. Before that the rear end had less than 1000 miles on it. My questions are:
1. Is this typically a coil spring issue or the shock or both?
2. How do I determine the correct replacement springs? I have wire diameter, OD, relaxed length and they are pig tail on one end. See pics.
3. What is a good source for standard length springs? Everywhere I look they are selling lowering springs only.
4. Should I use spring dampeners on the bottom for the pigtail and spring silencers for the top? There were silencers on the top side that have disintegrated.
5. Is anyone familiar with the type of springs needed for the spring tubes with a helical ramp like the ones from my pics? Looks like a progressive rate spring with flattened ends opposite the pigtail.
The shocks seem to be easy to identify and find. Just a matter of how much I want to spend.
Any help with spring identification would be greatly appreciated. :)

A couple of things I just remembered. I have been searching for springs assuming they were from the 1999 rear end with no luck. However, when I put in 1992 Mustang GT the springs I found seem to match pretty close. Almost like the builder did a mix and match between years. No. He did not give me the complete list of parts and receipts. Before you get on me about that please understand that I was just coming off of cancer surgery when I found this car and needless to say, my mind wasn’t 100% at that time. The car has been just what I needed at that time and I still love it.
Spring dims: wire diameter 9/16, OD 5.00”, free lg 12.50” (could be a little collapsed?).
