If I was in auz I would definitely do that but maybe better I can help you construct a copy of the tool. I started with a set from harbor freight you can also buy on Amazon but drilled out the largest five or six plates to a 1" hole to upgrade the push rod from the useless 3/4" that can handle 12Ton to bump it up to about 32T. You need to apply a shit ton of torque to achieve full power because lubricated torque spec on a 1" bolt is 750 ft·lb! (Works perfectly for me that's the max output of my impact wrench). The beauty of using the tool is the knuckles stay on the car and no allignment needed.
