Here is my experience and some pics:

It can be done with the cheapy kind (~$30) like I used but if you are going to use it more than once or twice, go ahead and spend the $175 or so and get the correct one with the center rod and plates on the ends. This is a case where the right tool makes the job faster,easier and safer.

I found that I could not get these types to work:

1) 2 exterior bars with cast hooks. Hooks were too thick to engage spring.
2) 1 interior bar with one pair of hooks and a spoon/spatula shaped end piece. You can't get the hooks engaged from inside the spring, not enough room.
