Why buy an expensive ass chain tool when all you need is a small piece of sheet metal and a pitman arm tool to press the rivet down!? Done it a thousand times never had one go bad. The pitman arm puller is $8 dollars at autozone. Place the steel along the tabs in the puller to make a good backing and press that shit down! P.S. Notice the nice little pin in the center of the bolt presses the rivet perfectly!
