I think the difference is the angle. that old school tool was meant for a 3/8" or 7/16" stud and the LSx's are much thinner and that tool uses more of an angle to compress the spring. The other tools mention are more centered on the stud to be used and then goes down from there.
I dont see how anyone uses that old school think on these new cars....
I could have this all wrong though....
