I just torque the rear spring on my 63 and thought I would share a picture on how I straightened out the rear spring to take the load off the differential cover to prevent broken ears. I used axle straps on the differential cross member and then a chain under the jack connected to the straps. This process forced the spring to straighten.

Hi! Larry

I had the same response when the process was explained to me over the phone by by a local chapter NCRS member.
You need to use two jacks and apply equal force to each jack when lifting or straightening the spring. The straps and the chains form a loop around the differential crossmember and under the jack. When you jack on the spring it pulls the frame toward the jack or keeps the frame from rising and straightens the spring. It only took about ten minutes.

That is a great idea Ray. Thanks for posting the pics. I have to put a new Eaton spring under my wife's '78 and that will save me some grief.

Take care,
Brian
