If not, it's only $10 there.
And it broke? Odd. It broke while turning the bolt? The fine thread hardened bolt? Did you use an impact on it?
It must have been cheaply made, try another one. I would spray it down too before hand with some penetrating fluid.
You might even want to try using the tool like when using a pitman arm puller. You tighten down on the hardened fine tooth bolt some, than whack it with a big hammer right on the end of the bolt, tighten it down some more, whack it again and continue like this over and over until it pops loose.
I want to look up the repair manual on this, what year Buick is this and what model/engine?
