I have an Oldsmobile service manual (1953) that states to use the tool J-720 for a certain job on the front suspension. A google search shows that it it is used in earlier manuals also, but shows no photos or descriptions. Does anyone have a picture of this tool, or knowledge of what this tool is and it's intended use? Any help is appreciated.

 

Not familiar with all the tool numbers. What particular job is it used for?

 

In my particular case, removal and replacement of upper pivot pin of the front suspension. It may be used for other things though.

 

Got the answer from the AACA forum. Looks like it's just an allen key
