Would have rated five stars except one end of each spring had to be heated and bent out. This was the most difficult job I have done on my 59 Apache so far.The old spring removes with no problem. The tough part comes when installing the new. I did try the washer method no luck or perhaps not enough washers. I built a jig ...no luck. Finally a five foot pry bar and help from my wife did the trick. Did I mention how scary it is to stretch these springs to the length needed to install ? By the way, very few of you guys bother to review products please help the rest of us and review products Thank you.
