Hello All! Just ran into this problem. Also, I am a new poster. 1990 Pontaic Grand Prix 2 door 3.1L w/ 314,5000 miles. The strut bearing plates are gone in the rear so I am trying to replace them. Thought I would replace the struts as well, but ran into the J37956 tool problem. This tool look like a modified C-clamp. You can see a pic of this by doing a Google search for 'GM tool J37956 '. My question: is there any other alternative at all?? I have not tried the C-clamp that I have and it looks like it will work, but my repair manuals recommend against it. Anyone else tried anything else? Thanks in advance.
