I am having to replace the lower ball joints on my '87 190D and I am trying to get a hold of the tool on short notice (this week). Can anyone tell me if this is a picture of the proper spring compression tool that I will need?

Also, if anybody is around the Houston, TX area and is willing to rent it to me or tell me where I can find one, I would really appreciate it! Thanks a lot.
